5mW Green Laser Pointers - The Handheld 532nm Green Laser Beam Beginning Pointer

If you are at all familiar with portable technology, you may be aware that the first green laser pointer to hit the worldwide market was the convenient 5mW. Since their first wide scale production in the year 2000, hundreds of varieties of 5mw lasers have flooded the internet shopping marketplace, saturating the industry with many poor quality diodes. The quick rush of popularity since the turn of the millennium has lead to a large increase in the amount of manufacturers and distributors throughout the globe, which has unfortunately lead to a plethora of poor quality diodes that are being sold on a large scale.

Now, not every single 5mw out there for sale on the web is a poor quality gadget. But it does mean that we need to be a bit more careful whenever we are shopping for a unit. There are a few simple things you can do to ensure that the 5mw you are planning on purchasing is a gadget of high quality production standards. Because lasers are high precision instruments, its worth doing a little bit of research to see to it that the unit you buy is a powerful and professionally manufactured goods.

First and foremost, what does the pointer model actually look like? Since the unit is going to be something you will be handling, be sure that you enjoy the actual design and casing of the device. Many different laser pointer pens are relatively small and convenient in size, but some pointers are designed a bit more bulky and cumbersome, so you will want to look at the sizing specs. The ideal product will be about the size of an average ball point pen, and is usually designed with a clasp so the laser can be gripped and stored very easily. The second thing you generally want to look at when you are browsing green handheld lasers, is what kind of expected life time can we expect from the diode. This will tell us roughly how much usage we can look to get, the average for a 5mw laser pointer is between 3000-5000 hours, so be sure that the product you are considering will be functional for this amount of time. You would not want to buy too cheap and have the beam die out within a week or two, so be sure to check the expected lifetime for the 532nm green diode.

Third, what is the price of the 5mw laser you are looking at? Laser pointers are goods where price directly effects the quality of the item. The lower the cost of a pen, almost always, the lower the quality. So you will want to keep this in mind, a unit under $50 is something to be very wary of. The diode may be of poor quality or the casing manufactured very cheaply, a preferred laser price for a 5mw green laser is between $75-$100 on the open market today. Yes, there are pointers out there at a lower cost, but historically these lasers have been of a far poorer quality than their slightly more expensive counterparts.

Lastly, and also most importantly, what type of warranty does the laser retailer provide for the particular unit? A reputable laser company will have no less than a 90 day warranty, and should at least provide the option for you to purchase an extended warranty. Statistically, 90 days is sufficient for a warranty, but having additional coverage can not hurt. Be sure that you buy from a laser that has a positive history and professional technicians. Even though 5mW is not all that powerful, a green laser pointer is a powerful tool and is to be used with great caution.

James has been working with 5mw green laser pointers since their first release in 2000. He has written extensively in the laser light technology field and prefers certified 5mw green laser pointers from professional laser source, biglasers.com

Powerful Laser Pointer

Powerful laser pointer is always an interest for laser pointer enthusiasts. But these enthusiasts are least bothered about the danger involved in these powerful units. Nowadays these can be seen on the internet as military lasers. This gave a chance to many people to use these high power laser pointers for their different applications keeping the dangerous aspect away from their mind. But before going with these high power laser pointers one should have greater knowledge and control over using them. If it is your beaten path then you can have them easily through the internet. As we all knew well how accessible the internet nowadays for all of us. Many people still knew only laser pointers as just key chain accessory and do not in depth about them. The present technology nowadays made so many useful gadgets using these powerful lasers successfully. Also now these laser pointers are coming relatively at cheaper prices. Astronomy lasers are best examples about the extensive usage of these lasers in gadgets.

This is important for every laser user, particularly when handling with 200mW and more should exercise more safety measures keeping in mind their safety. As the output of laser increases the intensity of the beam also grows to brighter and intensified. During this time there is a possibility for popping balloons. Users definitely know the capacity of this beam and what extent it could damage too. This is the reason all the users are strictly need to adhere to safety measures to keep against the possible danger of this powerful laser.

Green lasers are considered as more powerful lasers. Generally this green lasers frequency would be at 532nm. This kind of frequency generates brightest color and these green lasers are easy to convert in the initial stages in attaining more output. Generally through markets hand held lasers are kept at a minimum of 5mW green laser pointer and to a maximum of 100mW. Sometimes this goes till to 300mW too.

The present technology has given us cutting edge over the developing trends. But while approaching some of them enough safety measures should be exercised if not will result into hazardous situation. Particularly when using powerful laser for various purposes. The easy availability has triggered more danger among us as many people without any knowledge too opting for these lasers. This kind of situation limiting the access to powerful lasers could help the situation to keep under control. It is true there are benefits too in using powerful laser but only an expert can made them utilize to that extent. This is the reason everyone should think more about these powerful laser pointers and their extensive usage in nowadays. Acting according to the situation is very much needed with the powerful lasers. Availability of these laser pointers should be limited to experts only.

When a Green Laser Pointer is the Perfect Tool

There are thousands of different varieties of a green laser pointer you can buy online for just about any application that it may be needed for. So how do you know when a laser pointer is the perfect tool for your needs? There are a few simple things you can keep in mind when considering any gadget.

1. What do you need the laser for?

This is a pretty important question because it will ultimately determine what type of green laser you go with. For instance, if you are going to use it for spotting purposes or for search and rescue where you will need the laser to produce a bright beam for several miles or more, its important to get a high power model. If you are only using it for a presentation or speech you may be giving then you probably want to consider a smaller power of laser.

2. Will the laser really help you out?

This question will be easier to answer for some individuals who know what they will be using the pointer for. Lets consider some applications for a laser: star gazing for astronomy, laser sight lining, military deployment for targeting & intimidation, scientific experiments, or to simply have fun. A green laser pointer can be ideal for certain applications especially those where distance is important. Green is produced at a beam of light at 532nm which is the brightest light frequency in the visible light spectrum, which just means that green appears as the brightest color to the human eye.

3. Is a laser to cheap or too expensive?

Because every manufacturer uses different materials and costs to produce their products, the price will change from model to model. This will probably be one of the biggest determining factors whether or not you buy a laser, so its important to compare items of the same power as far as their price is concerned. You will find different prices for different models, even though the power may be the same. For example, you may see a cheap 100mW for $99 and a 100mW for $299, so how do you know which is the better laser?

Well, one's that seem too good to be true usually are. The cheaper green laser pointer models out there will not have certain safety measures and features that lower the value and therefore the quality of the piece. Think of your budget and where it stands, then look for the best quality laser within that price range as this will actually last you. A very cheap laser can burn out in less than a week and have no warranties making them obsolete and a high risk purchase. A high quality pointer may have a slightly higher sale price online, but will last a long time and have a valid warranty to back the laser up.

There are a few things you should always keep in mind whenever you are considering a green laser pointer as a tool you need to buy. Remember that too cheap does not mean a good deal and to put in a little bit of research to ensure that any laser that you do like meets a few quality standards that you have set yourself. If you are going to spend on a laser, you want to make sure that is the best valued laser pointer money can buy.

James is an avid Green Laser Pointer fan and owns over 50 varieties himself. He prefers lasers from reputable sources like Thinklasers.com, the web's leading United States based source for Green Lasers.

The Laser Pointer In Its Tracks

Global laser technology has always kept up with the ever changing demands of the times, Laser pointers in particular have evolved to become the example of this huge success, though there was a time when it seemed hard to get hold of these laser pointers. The advent of technology reduced the bulky looking green, red, blue laser diodes to fit in the palm of the hand proving its portability and convenience.

Because of the laser pointer's compact power and distinct features the stunning green laser beam has proved to be the popular choice boasting as much as 532nm in frequency while consuming no more than 5mW in output power. On top of that, its brightness can be seen in the light of day and in the dark of night with such clarity proving to be the next door tool for those who have a knack for astronomy.

More often than not, the arrival of so many varieties of laser pointers, proved to be a tough choice for enthusiasts, being faced with such dilemma including what to choose and what to avoid. Some offer cheap options, others offer easy access, the red laser pointer in particular proves to be an investment to avoid especially for the those who invest on quality and good value.

True to its word, the high power laser pointer is a sound investment for the serious laser pointer hobbyist, Its key features like durability and high output power eliminates the need for modification which oftentimes may damage your laser pointer diode.

Now there are other choices in the market like the exotic 473nm blue laser pointer and the recently introduced orange hand held laser. The fast paced technology at the back of these modern day inventions has benefited the global laser community providing compact yet powerful lasers.

Safety has always been a question that strikes the minds of its enthusiasts and its future hobbyists. Yes, its fun to go laser pointing at this hand held wonders in different directions but one must put in mind that it has responsibilities that entail each mindful laser pointer user as it poses legal predicaments...Don't go pointing lasers at this compact wonder amongst people, animals or moving vehicles like cars, trains, airplanes as it may be illegal and may slap you with legal charges. Keep in mind that these are not toys, it is fun to have them around but just be mindful on how to use it.

The laser beam in its tracks have evolved to take the whole planet by storm, more enthusiasts are getting their hands on these laser pointers as they are widely accessible and easy to use.

The evolution of these thingamajigs from its humble beginnings of the red laser to the lasers of today makes you just want to get your hands on these small wonder, and there is no better time to grab your own laser pointer, now definitely is the answer to beat...Just remember safety comes first.

Laser Pointer Maintenance - Proper Ways to Maintain Your Laser Pointer

Laser pointers are not cheap gadgets. Depending on the power of your laser pointer and where you made the purchase, it could easily cost you hundreds of dollars. It is therefore very important to take good care of your laser! Laser diodes within your laser pointer or portable laser are usually rated for at least 5000 to 8000 hours. If maintained properly, it shouldn't have any issues exceeding the rated usage time. In practical terms, if you use your laser for 2 hours a day every day, your laser should last you for 7 to 11 years!

Laser Maintenance Guidelines:

When not in use, remove the batteries. Leaving the batteries inside any electronics device may cause corrosion of the battery terminals leading to other problems.

The aperture lens of your laser pointer is very sensitive to dust. Even a small spec of dust on the lens will cause your laser to have a "spotted" laser beam. Therefore, keep the lens covered when your laser is not in use. If you do not have anything to cover the aperture, use a small piece of masking tape. Some portable lasers have lens covers to prevent the entry of dust, keep the lens cover closed when your portable laser is not in use. If the lens does become dirty, make sure to clean the lens using proper cleaning procedures as provided by your laser's instructions manual.

Stored it in a dry place ideally in room temperature. The humidity should be no more than 45% with temperatures between 0 to 40 degrees Celsius.

Lasers are sophisticated electronic devices with delicate optics. Handle your laser gently and with care. Do not drop your laser pointer.

If you follow this guide, you should have no problems exceeding your laser's rated lifetime.

eBay Laser Pointer Scam Exposed

The scam itself is based on the type of light given out by the laser pointer, the way power is measured, changes made to the laser pointer and ignorant and/or dishonest sellers.

Type of light

These lasers are advertised as green lasers and should give out green light and only green light. That how ever is not the case. Virtually all supposedly high power green laser pointers on ebay emit a combination of green light with a wave length 532nm light and infrared light with wavelengths of 808nm and 1064nm light.

All genuine high power green laser pointers have a built in filter that prevents them from emitting infrared light. The laser pointers on eBay are missing these filters which have either been removed or deliberately manufactured with out. Removing the infrared filter from a laser pointer increases its power and makes it a lot more dangerous.

Take a 240mW laser pointer commonly found on eBay as an example. This laser pointer is likely to have only 40mW of green light with the remaining 200mW of light being infrared light. Customers pay for laser pointers with 240nm of green light and only get laser pointers with 40mW of light. Effectively cheating them of 84% of their money.

The other problem with missing infrared filters is the lasers are very dangerous. Infrared light spreads out like a torch beam compared to green light which is in a narrow beam. Green light being visible can be avoided but the Infrared light because it is invisible cannot be avoided. Most safety glasses that protect against green light are completely transparent to infrared light. This means a person wearing safety glasses and using one of these lasers is less likely to avoid the beam and much more likely to suffer damage to their eyes.

Measurement of power

The power of most laser pointers will peak in the first few seconds then stabilize at a level much lower than the peak. Reputable sellers will give the average power as the advertised power. Ebay sellers on the other hand use the peak power as the advertised power. This is very deceptive because it misleads people into thinking the laser is much more powerful than it really is.

Modifications

These laser pointers are only designed to handle powers from around 5mW to 10mW. The sellers modify the laser pointers by increasing the power from the batteries to the laser diode so the diode emits a more powerful laser beam. The problem with this that the diode is not built to handle the higher power and will have a much shorter life cycle and is likely to burn out. Many ebay lasers lose power or burn out completely in a matter of hours or even minutes. The lens in the laser pointer the acrylic coatings are also not designed for the increased power and are likely to damaged with reduced performance or fail completely.

These eBay sellers are not laser experts and generally have little or no understanding of the laser pointers they sell. This means they are not able to give qualified advice or recommendations and the level of support and service they can provide is minimal. Their general response to customers when there are problems with laser pointers is to ship it back for a replacement. Given that the cost of the laser is not much more then the cost of shipping it, most customers cut their losses at that point.

Possible remedies

Laser pointers with powers over 5mW are classified as hazardous goods and are not allowed on eBay. If you have been scammed by one of these sellers, you can threaten to report them to eBay and they may have their account suspended or even closed.

If you paid with PayPal, you can also open a dispute for goods not as described. The dispute may not be decided in your favor but most sellers are willing at that stage to issue you a refund. If you paid with a credit card, you can start a charge back with your credit card company in a similar manner with a greater chance of success than PayPal.

The last option is to bluff. Claim that you will contact eBay, the police and the government department in charge of consumer affairs in their country if they do not issue you with a refund. Considering they are selling an item prohibited by eBay and illegal to sell (legal to possess) in a number of countries, this bluff is very effective.

Portable Handheld Lasers - The Laser Pointer Buying Experience That Burned Us All

Hand held lasers are by far the most practical form of technology, and for good reason. The small size makes the lasers very convenient and portable in size, so taking the pointers into the field to conduct research has been gaining popularity amongst many astronomers as well as medical and military professionals. But not all portable handheld units are worth buying, often times, the products have been manufactured rather cheap and can burn out far faster than a high quality device should. There have been stories of expensive laboratories experiencing major problems with the cheap laser pointers they had acquired, if you want to ensure that the hand held unit you buy is worth using, there are a few key pointers to keep in mind.

First, what exactly are you looking to accomplish with your portable handheld laser pointer? Does the beam need to output over any set distance? What color frequency are you looking for and how much output power does your application require? These are all simple questions that you may want to answer before you start looking to shop for a portable pointer. Lasers are high-tech gadgets that can come with a hefty price tag, be sure that you are ready to do a little bit of research into any hand held module before you order one from a retailer. All portable lasers are not created equal! A little bit of knowledge about any particular handheld unit can not hurt your situation, in fact the more you know about the diode, casing, expected life time, etc., the better off we will be when we are looking to buy lasers.

There is a lot we can do to ensure that our purchasing experience does not leave us shocked or embarrassed in any way. You may have heard horror stories about hobbyists who would turn to eBay to buy their laser pointers, looking to save a few dollars here and there. The problem with this was that the units being sold on eBay turned out to be the lowest quality laser diodes available anywhere. There have been reports of people receiving completely broken pointers, or even worse, not receiving anything at all. When you look to save a few pennies, be sure that you are not buying something from a teenager in their basement with an eBay seller account, you will get burned! Your best bet whenever looking for any variety of handheld portables, or even industrial laser modules for that matter, is to work with a reputable retailer who specializes in the specific type that you are looking for.

More often than not, you will find that the cheapest laser pointer available is not going to be the best deal. These consistently burn out far quicker than the company had advertised, and usually a little rain or a drop of water will ruin the product for eternity. This is why its so important to know where your purchase is coming from, do a little research on the provider you are looking to work with. Are they visible anywhere on the search engines, like Google? How does their pricing compare to that of competing laser companies? Do they provide any support, in other words, can you get questions that you have answered?

High power portable lasers are investments, be sure that you are securing your investment with laser warranties and a high quality laser retailer with search engine recognition and various methods of customer service. Do not be afraid to ask the laser company a question or two, if you are going to buy lasers from them, be sure you are dealing with individuals who know what they are talking about. A few simple precautions along with a few Google searches can teach us a lot about any laser model or particular company. If you are serious about buying portable hand held lasers, do yourself a favor and look into the laser source as well as the model that intrigues your interest. A good laser should last for a life time of enjoyment.

Find the Best Green Laser Pointer to Buy Cheap Online

With so many different green laser pointer varieties for sale online today it can really be difficult to find what is really the best deal. Different laser retailers and websites will offer different models so its important to know what you should be looking for in a high quality laser pointer that isn't too cheap or shoddy and that provides a certain level of quality when being used.

Recently it has been the green laser who takes the crown as far as laser popularity is concerned, no more is red the only beam color you can get your hands on. There are a lot of different laser pointer colors like blue, yellow, purple, as well as infrared but it is green at a frequency of 532nm that has become the most popular. This is primarily because each green laser produces a visually spectacular beam that appears brighter than any other color at the same output powers, so it really does look the brightest and is therefore used most commonly.

The problem, however, is that most laser manufacturers rush their production or design and develop a laser that is worthless in the long run. Sure it may shine brightly in the beginning, but you want a green laser that is going to last more than just a few days. You want to buy a green laser that is going to last for years, even decades to come. Like most goods of varying quality, laser prices change greatly from one model to the next and the cheapest price really never is the best laser online. So you want to consider that, don't short change yourself because you think you're getting a deal when you're paying for something that is going to just be terrible.

Laser pointers can be pretty complicated technology and today's best green laser pointers incorporate all of the required laser safety features the FDA demands, but these lasers are only available through certain brands and retailers. If you are looking to buy a laser that is really worth your while you need to do some research and see a video or two, even read a review or forum post from actual users of the laser. The more you know about any green laser model the better off you will be when you decide to make a choice in which laser you are going to buy. 100mW is a very powerful starting point, so you may consider using a weaker 5mW green laser to get accustomed to laser use.

Whatever laser pointer type you decide to buy, be sure it has a warranty and a long expected life time. After all, if you're going to pay for something you probably want it to be the best quality available. Don't trust what the manufacturer says, trust what other users are saying and you're gut and you'll find yourself with a great laser that didn't break the bank to buy cheap.

James is an avid laser enthusiast whose prefers each green laser pointer developed through USA based Think Lasers, for quality and a cheap price that fits the bill. He tests and recommends serious laser fans to buy green lasers nowhere else.

Best Green Laser Pointer Technology Now Used by the Military

Laser pointers have become a great tool in the military world for both training exercises as well as in the heat of combat. Advances in laser technology have made more powerful lasers readily available in smaller more convenient sizes that can be used by different branches of the armed forces. Whether mounted to a rifle or being used as a hand held spotting device, soldiers find green lasers extremely useful and a great asset. But there is always going to be the questions as to which is the best green laser pointer, so to help make the proper decision are some important things to consider before buying any laser for yourself or someone you know in the military.

1. What is the laser actually going to be used for?

This can have a huge factor into which type of laser will be the most ideal for you as different lasers have different applications. When looking at green lasers you want to have something that is relatively strong, 50mW or higher is a good power outage for use in the field of combat, but stronger can also be useful as it has a great range. When using the laser as a tool to be extracted when in hostile territory, a powerful green laser beam is indispensable to spotting the troops who are to be picked up.

2. What type of laser design is the most practical?

Now, most laser pointers have a similar design, the usual pen shaped laser, but there is also some variety available these days. So what is the most practical and useful laser design that can be used by someone on the ground, in the heat of combat? A design that is able to be mounted to a rifle will be very useful and provide a great advantage to whoever is using it. This means that a smaller design will be the most effective as some of the larger laser units are too bulky and can actually impede the sight of a soldier while also adding too much weight at the same time.

Also, what the actual laser body is made of is important to consider. If using a laser in combat its important that the shell of body of the laser is crafted with strong materials. Some of the world's best lasers are made with strong aircraft grade aluminum or black polished brass which are both light and sturdy. The stronger the laser body the less chance that it can be damaged and malfunction.

3. What type of batteries does the laser use?

This is one question that isn't considered that often but is actually crucial when considering a laser for military use. Because some lasers use a power source (battery) that need to be plugged in and recharged it can be great when used at home, but when in the field away from a power outlet it can become an issue. More often than not a soldier will be able to replace batteries with new ones as opposed to re-charge a current battery. Therefore a laser that uses common batteries like triple A's or AA is the most valuable to an armed service member, where new batteries can be replaced without the need of lengthy charging.

Not all laser pointers are created equal and not every laser will find itself useful for military applications. Only the best green laser pointers should be put in the hands of men and women on the front lines, both for their protection as well as there ability to be aggressive and intimidate enemies. If you're looking to buy a laser for someone you know in the armed forces, be sure you do some research into what they may actually be able to use and ensure that the quality of the laser is of the highest standards because it can literally be a matter of life and death on the battle field.

James has been involved with lasers for more than a decade and knows first hand how the best laser pointers can provide great value when used as military lasers.

How to Buy a Laser Pointer - A Guideline on How to Buy The Right Laser For You

The different types of lasers

Color

Lasers are now available in red (632nm), green (532nm), blue (473nm), orange (594nm) and infrared (808nm to 1064nm). The color of the laser determines the visibility of the laser, the attractiveness of the beam and the price. The color of the laser does not determine the power of the laser.

Power

The power level of lasers is measured in mW which is an abbreviation for milliwatts. The available powers range from less than one mW to over 400mW. Power is one of the key factors in determining the possible application of a laser and the price of a laser. Power also determines the danger of a laser.

Size

The size of lasers can range from the size of a small AAA battery to the size of a base ball bat. The two most common sizes for lasers are pen sized laser pointers that are small enough to fit in your pocket and larger hand sized portable lasers.

On/off Switch

Lasers can come with two types of switches, momentary off/on pressure switch and a standard click off/on switch. The type of switch determines whether the laser can be used hands free or not. A large number of applications require are not possible with lasers that are not hands free.

Safety features

Safety features can range from none to an elaborate range of keys, dongles, lens shutters and time delay.

Which laser should you get?

This depends entirely on what you want the laser for and your budget.

Presentations

Blue and green lasers are best for presentations with blue being the most impressive and also the most expensive. One very important point with buying a presentation lasers is power. Never buy a laser with more than 5-10mW power because of the danger to your audience and your self.

Laser pointers are best with a convenient size and no need for hands free operation.

Astronomy

Green lasers are the only color that should be considered for astronomy. Required power varies depending on the number of people you'll be with. As a general guideline, the more people you are with, the stronger the power of the laser. Generally a 15mW to 35mW will be more than adequate. For pointing by hand a laser pointer is ideal. For mounting on a telescope, a hands free medium sized laser is best.

Burning

For common burning applications such as lighting matches, cutting electrical tape and popping balloons, 95-125mW in power is more than enough. If money is less of an issue and you want to be able to light cigarettes, burn clothing and melt plastic, you would need at least 150-200mW in power.

Color is not an issue because the only high powered lasers available are green.

Out door pointing

To have a beam point that is clearly visible in direct sunlight at long distances, at least 55mW in power is advisable. For applications such as alignment, a laser with an on/off switch and efficient heat sink would be ideal

Non lethal deterrent

For maximum effect and impact, at least 200mW in power would be ideal. The higher power would allow the laser to deter people faster at longer ranges. In a tactical environment, portability is also an issue and smaller lasers such as the Spartan series are ideal.

Buy Green Laser Pointers - A Laser Pointer Price Guide For Buying Green Beam Success

If you are looking to buy green laser pointers you are going to want to do some research to ensure that the laser pointer you are purchasing produces a solid 532nm green laser beam. The reason that research will be vital here is because there are just too many green laser pointer distributors out there on the web, and the fact is that not all of them ar 100% trustworthy.

So listen closely as we cover some major points that will help you achieve green beam success when you are trying to buy green laser pointers at a reasonable price. First and foremost, you need to determine what exactly are you looking for. In other words, what sort of laser applications are you going to be performing? Does the green beam need to be powerful in output power? Do we need a constant on/off laser engagement switch or is a temporary push button sufficient? Are we considering distance, and if so how far will the green beam need to be visible for? So before we even start doing research on where to shop, we need to really sit down and determine what is our laser going to be used for in the first place.

When you have a clear idea of what your laser tool will be used for, then we can begin to crawl the web looking for the finest quality diodes that we can purchase at a reasonable price. There is, however, something that any hobbyist or professional must keep in mind: Buying cheap is not necessarily going to mean you have gotten the best laser deal. More often that not, the cheaper, lower cost laser pointers are manufactured with poor quality green laser crystals and housed in less than adequate laser casings. This can save you a few bucks, but what is the point of a few pennies saved when your laser burns out within the first two weeks and you find yourself searching the web yet again looking to buy a new unit. So if you are going to spend a little money on the device, do yourself a favor and do it correctly.

When you see a module that you like and which falls within your budget, then you can really start to consider placing your order. Be sure that the retailer you are working with has reasonably priced lasers. The market for buying pointers is relatively competitive, a lot of companies are offering the same goods, so a little bit of market research can tell you very quickly which laser company is providing the best deal. No sense in buying the same 95mw green laser pointer at $300 when you can get it for $200, right?

When you have found a reliable source, be sure to take a look at the laser safety equipment they are offering as well. Lasers, though electric and brilliant in their performance, can be very dangerous if used incorrectly. You must always keep the safety of others and yourself a number one priority so that the beam does not cause any bodily harm to people that are present. Take your experiments seriously, and your casual use as well. It does not take too much dense light to damage a persons retinas, so be careful where you point your laser.

Finally, be sure that the green laser pointer you are going to buy has some type of warranty attached to it. Sometimes a laser will burn out prematurely, but this is ok if you are working with a top notch laser company. They will gladly replace the green laser for you, free of charge, if you have found the right retailer. So do your research, and buy green laser pointers with a good knowledge about what is out there so that you can make the best educated consumer decision and get the brightest green bang for your buck.

James has been buying green laser pointers since they were first made available to the public. He has designed various green laser accessories and written extensively in the laser light technology field. His preferred laser provider is certified BigLasers.com, where he personally chooses to buy green laser pointers.

Spyder II GX-BX Laser Pointer Series Review - The Worlds Most Powerful Green and Blue Laser Pointers

There is little that can be said against the world's most powerful elite hand held laser pointers anywhere, also known as, the Spyder II GX/BX. These one of a kind units are the most spectacular burning military lasers ever made available to any and every gadget hobbyist on earth. From 200mw to 300mw for the Spyder II GX/BX 532nm green module and 15mw to 30mw for the Spyder II BX 473nm blue model, if you are familiar with milliwatts (mW) output power, you will see that this is extremely impressive for a portable diode.

As a matter of fact, the green Spyder has been recognized as the world's most powerful laser pointer by the Guinness Book of World Records circa 2007, giving great credit to the technicians and designers behind the scenes of the revolutionary product. The Spyder series lasers are also waterproof devices, capable of being fully submerged even up to 200m. The durable aircraft grade aluminum case, light weight, and waterproof design, adds to the versatility of the powerful pointer and has given the military great reason to obtain thousands of Spyder II Units. Military personnel throughout Iraq, Afghanistan, and other nations of the world (including non US military personnel) have utilized the extremely intense output power of the 532nm green Spyder beam to intimidate insurgents, conduct reconnaissance, as well as pinpoint targets.

But is all of this burning laser power fit to be in the hands of untrained laser civilians? The verdict is still out on the widespread availability of high power laser pointers throughout the globe as more and more powerful lasers are being utilized by various individuals for personal and professional use. In the US, the argument is that high powered laser pointers should not be legal to own and operate in the united states unless the device meets specific laser safety standards. This is an understandable argument and concern, but it has in no way stopped the safe use of powerful laser pointers to buy and sell online through reputable laser retailers. What it seems to boil down to is the laser user themselves that will determine how dangerous any laser item will be. A trained and cautious user will undoubtedly cause no harm to themselves or anyone else when they engage their laser. However, the opposite is possible for an untrained laser hobbyist who lacks caution on certain regards that should be considered because of the high power light radiation being emitted by the powerful laser. Whatever your own viewpoint, education is the answer. Only proper laser education and controlled use will prevent future laser hazards from occurring.

The Spyder laser pointer is in no way related to your average laser pointer pen and your Spyder II GX/BX review should be a long and thorough one. Whether you are considering a 532nm green or 473nm blue Spyder laser, note that it is an investment. That's right, an investment. You will undoubtedly fall in love with your Spyder at first site and will enjoy it for years. Just be sure that you understand what kind of laser pointer you are about to buy. There is no other like it on this planet and you must exercise extreme caution when using such a powerful laser pointer. There are hundreds of YouTube videos that will demonstrate the power of a Spyder II GX (popping balloons, lighting matches, burning electrical tape, etc.) if you give a minute to look. Through all of the hype and buzz surrounding the GX and BX, the Spyder laser pointer has proven itself time and time again to out due any similar laser on the market. The difference in quality is so substantial that many Spyder laser users have sworn to never "downgrade" their laser collection with anything less. This may be going to extremes, as you may know there are hundreds of impressive laser models out there, but a Spyder controller is a particular breed of laser pointer owner, with a true passion for lasers.

James has been involved with various laser pointers including the Spyder II GX/BX laser pointer and has written and spoken extensively on the incorporation of lasers into our modern world. His preferred retailer of certified spyder laser pointers is big lasers.

Green Laser Pointer - Modifying Your Green Laser For More Power

A green laser pointer produces a far brighter visible beam than any other color of laser. This is not necessarily because the lasers are modded to such high powers, but instead because green is the brightest color in the visible light spectrum to the human eye.

This is why the lower power 5mw green laser beam is clearly visible under the cover of night or a little bit of smoke. Still it seems this is not enough for most laser enthusiasts out there, they feel a need to modify their laser pointer to increase the strength of the beam, with little regard to the obvious safety hazards.

A green pointer with a simple on/off push button switch is not legally allowed to be sold above an output of 5mW in the united states and many other countries. This makes getting your hands on high power green lasers a little bit more tricky. If you know where to look, you can easily pick up high quality hand held and industrial laser goods right from the web through reliable retailers with no hesitation. But, if this is out of your budget and you're looking to buy green laser pointers cheap you may consider modding your pointer.

The 532nm green laser crystal can be a bit less complicated to work with than that of a red laser pointer, which is yet another reason why green lazer pointers are so popular for laser modification. A simple sottering kit will be needed to complete this task, oh and of course your laser. Now, if you have a high power green laser, there is no sense in toying with it because there is always the possibility for complete failure or permanent damage to your laser pen.

So, unscrew your lasers end-cap and carefully remove the batteries or power source. You may be able to see the green diode and even remove it if you have a real cheap laser, but most likely this won't be the case. A lot of laser manufacturers have made getting at the diode rather difficult, not so we can't mod them, but so the laser stays in its solid state and remains durable. These are high precision crystal diodes and one variation can lead to a dispersed beam.

If the diode is removable you are in luck, if not, I'd let the professionals handle your lasers. Spend the money, you will not be disappointed. But for all of you cheapskates that want the cheapest green laser pointer possible, and I feel where you are coming from, we need to remove the diode and locate the green laser crystal. You will notice it is round, maybe the size of the flat end of a pin, and looks like a CD or DVD laser eye. You will need to heat up your sottering kit and put on some safety goggles.

Now we very carefully heat the diode until the crystal has been visibly changed, its great to have a few diodes laying around to get the hang of which way the green crystal needs to be heated for proper beam propulsion, but make do with what you can. After you have heated and molded the crystal, from a round shape to an oval shape preferably, replace the diode into the laser casing. Return the pointers batteries and end-cap, then turn your green pointer on. Has the beams output power been increased? You will be able to tell immediately if you have drastically increased the output of your green laser, but if the change is slight or you have ruined your laser we may be out of luck.

I'm suggesting if you want a perfectly collimated long lasting green laser pointer, you purchase the higher output powers. These high tech gadgets come with warranties and there is no risk in losing your pointer entirely. But for everyone on a budget who really needs a 50mW green pointer or higher, you can always try (I want to stress the word TRY) to mod your green beam at home. Either way, be careful with all lasers.

James has been a laser hobbyist since he purchased his first green laser pointer and has modded hundreds of them since. He prefers professional laser tools, but enjoys the occasional "home made" laser. His professionally certified Green Laser Pointers come from BigLasers.com

Buy Laser Pointers - Laser Reviews, eBay Disasters, and Online Pointer Shopping Success

Laser pointers are high-tech tools and if you are shopping to buy one there are a lot of different things you will want to keep in mind, not only to protect your technological investment, but yourself as well. Many lasers that are available today have high output powers and will require a certain level of laser safety to handle properly because you are dealing with dense light radiation.

Now, we all know how practical and useful lasers can be, so if you are wondering where can I buy laser pointers? all you need is an internet connection and a little bit of tech savvy insider information to make the most of your dollar. Now we're most likely not looking to 1$ buy wholesale lasers, we're going to want something that is going to last a while and whose diode will really be professional grade. So when you are browsing the internet be sure you are using a reputable laser retailer.

I would stay away from buying lasers on eBay all together. From my own experience, and the horror stories i've read about, the lasers people purchased from eBay were nothing more than cheap green pointers not even worth using. You are really getting hurt in the long run, even if you save a few pennies here and now. What's the point of shopping for a laser pointer, putting in your own time and research, to throw it all away to some kid in his basement with an eBay account selling his used lasers? If you want the best, or even just something worth holding on to, we have to turn towards the broader horizon that is the internet as a whole. There are a good number of qualified laser suppliers who can provide many different varieties of laser pointers and modules that will last you years to come.

But before you take the step to get your laser, make sure you have an idea of what you are looking for. What sort of applications will the pointer be intended for? How much bright power are you looking to shine? What color frequency should the laser beam be? All questions we need to have answered before we start looking, unless we are simply a laser hobbyists looking to add to our collection of course.

So when you have an idea of what type of pointer you are looking to buy, its time to get out there and find who has the best quality product for the lowest price. You can always find a laser review on the pointer you are shopping for, but many times these are not un-biased reviews. More often than not that company has "reviewed" the item themselves, if you know what I mean. None the less, they will provide some good info about the laser itself if nothing else, so its still a good idea to browse.

When you've found a laser source who sounds reputable and has some positive customer ratings, then you may be ready to buy a laser pointer. Remember that like any other good, you get what you paid for, the cheapest price isn't always the best deal. High power lasers are a little more expensive for good reason, this is medical and military grade technology that we are able to buy freely. Do not under estimate the power of any laser pointer and don't buy laser pointers for your children!

bio: James is an avid laser pointer enthusiast and urges anyone shopping to buy laser pointers to do the proper research. He has been working with laser tools for over 15 years and has designed various laser accessories. He will only buy laser pointers from professional certified laser providers, his distributor of choice is Big Lasers.

5 Things You Should Never Do With a Laser Pointer, Portable Laser Or Even a Laser Module

1 Look directly down the laser

Some people out of curiosity, trying to fix a fault or just out of sheer stupidity will look down a laser into the lens where the laser beam comes out. I don't care whether your finger is off the on button, you've taken the batteries out or if the guts of laser are spread all over your work bench, you NEVER look down a laser. You would never look down the barrel of a rifle and in the same way you should never look down the laser.

Most eye injuries with portable lasers have occurred when some one was looking down their laser thinking it was safe. A classic case was when a laser enthusiast looked down their laser when cleaning the lens only to realize too late that they forgot to take the batteries out. That person now has a permanent blind spot in their eye.

2 Point the laser at aircraft

This looks like a very obvious not to do with a laser but judging from the amount of people out there pointing lasers at aircraft, it is not obvious enough.

Apart from the safety and hazard issues involved, pointing lasers at aircraft is a federal offence in just about every country. So if you want to end up in federal penitentiary breaking rocks for the next 10 to 20 years, please go ahead and be my guest.

If there is one thing that sensible laser enthusiasts hate, it is people who point lasers at aircraft. Not only is it dangerous and incredibly stupid, it is also responsible for over regulating portable lasers to a point where the hobby may not have a legal future.

3 Point the laser at people

Another obvious "not to do with a laser" that too many people out there don't seem to understand. High power lasers are dangerous to your eyes so if you point a laser at some one, there is a chance you will injure their eyes. It is that simple.

Sure you might just be pointing the 500mW laser pointer that can light cigars at their hand, the back of their head or on the bridge of their nose where every one knows is safe. What happens though if they move, your hand slips, some one bumps you or any one the many things that can go wrong do go wrong? What happens is in that one split second you are responsible for that person losing partial to complete vision in that eye.

4 Use the wrong equipment or method to clean the lens

The most common cause for damage to laser pointers and even laser modules (apart from being dropped) is people clean the lens incorrectly. The lens in lasers is a precise and delicate optics that is easily damaged so great care needs to be taken when cleaning them. There are a lot of methods for cleaning lens ranging from tissues and t-shirts to microfiber and lens pens.

The only completely safe methods of cleaning laser lens is to gently blow compressed air on the lens and to use professional optics cleaning tools such as lens pens. If you do use some material such as cotton buds, make sure you also use a fluid such as lens cleaning fluid. Cleaning the lens when they are dry will just cause dust on the lens to scratch them.

5 Modify lasers

Modifying a laser is when you use one of several methods to increase the power to the laser diode so the laser beam has more power. All lasers, whether they are laser pointers or laser modules can be modified and it sounds like a very cheap way to get a high power laser.

The problem with modifying lasers is that lasers are not designed to handle the increased power levels and modifying them will normally damage or destroy the lasers in a matter of minutes. If you don't mind ruining your laser or you are interesting in modifying your laser as an experiment, go ahead. If on the other hand you've spent several hundred hard earned dollars to buy your laser, leave it as it is.

High Power Laser Pointer & Portable Laser Applications

"A solution looking for a problem" - Charles H. Townes on the application of lasers.

Since lasers were developed, they have had numerous applications in a number of diverse fields. Listed here are just some of the application for high power laser pointers and portable lasers.

Astronomy

With a brilliant beam stretching for miles into the night sky, high power green and red laser pointers are excellent tools for astronomy. Easy and quick identification and pin pointing stars and other celestial bodies. No need for difficulties, frustration or wasted time pointing with your finger or trying to explain. A laser pointer can be used to identify and pinpoint any object in just a few seconds.

High power portable lasers can also be mounted on telescopes as a visual indicator of where the telescope is pointing. Portable laser is also ideal for mounting on GOTO mounts/telescopes to help direct other people with telescopes and binoculars to an object. With no duty cycle, an on/off switch and very durable construction, a portable laser can be both conveniently and easily mounted on almost any make of telescope and used by hand.

Red light is scattered less by the atmosphere than green light because red light has a longer wave length making green lasers more visible and suitable for astronomy. The light from green lasers also has the advantage of being the wavelength that our eyes are most sensitive to.

Most cheap low powered laser pointers are not effective to be used in astronomy. The beam from these lasers is too weak and easily obscured by ambient light, smog and fog. The beams from high power laser pointers will easily be visible at night in the worst of conditions with the higher powered models even being visible during the day. Perfect for dawn and dusk astronomy.

Photography

Lasers are visually stunning and are used to create very impressive and dynamic photographs. When a camera is used on extended exposure, a high power laser pointer can be used to draw, make pictures and create marvelous visual effects. The proliferation of laser photographs online is a testament to the popularity of lasers and photography.

Lasers and photography is not just limited to lasers pointers and hobbyists. Specialist lasers with short powerful pulses make high speed photography with exposure time of several trillionth of a second possible.

Aiming devices

As a sports person out for some target practice or a soldier on the battlefield, high power laser pointers can help you improve your aim and accuracy. With a range well in excess of 10 miles at night, laser pointers will give you the ability to line up any target in visual range. Even in broad daylight, the green laser dot will be a visible aiming point that can greatly improve accuracy.

Construction/Alignment

On construction and building sites, high power laser pointers and portable lasers are ideal for engineers and site mangers to point out details and features. The laser beam dot is clearly visible in all conditions allowing the quick and efficient identification of features on a site. Effectively saving money through the reduction of wasted time and minimizing errors.

Laser pointers are also used for aligning objects over long distances. High power laser pointers are commonly used by both road construction crews and ground keepers at major sporting venues, world wide.

Avian dispersal

Farmers, airport ground controllers, pet owners and naturalists all use portable lasers as a non lethal method of avian dispersal. Lasers have been instrumental in the reduction of bird strike rates and in effective avian predator management for a number of protected bird species.

Both laser pointers and portable lasers are used by farmers from various countries to supplement their avian dispersal programs. By using our lasers, farmers have been able greatly reduce their cost (rifle or ammunition costs) with zero impact on wildlife and still adhere to local laws for wildlife protection.

Laser shows & entertainment

No rave or dance venue now is complete with out a laser show. The same can be said for any major out door event with the Asian games, Commonwealth games, Afro-Asian games and Olympic games being classic examples.

Both high power laser pointers and portable lasers can also be used with basic optics to create similar light shows on a smaller scale. The shows you can do with lasers range in complexity from a simple star diffraction grating to a more elaborate set ups with galvanometers and dichroic mirrors.

Medical

Lasers in medicine have a wide range of applications range from vision correction and surgery to wound cauterization and the acceleration of soft tissue healing. In brief, the lasers used in are divided into two categories, high power green lasers (3000mW to 10000mW) and low power red and infrared lasers (1mW to 500mW).

High powered lasers are used to cut through tissue and seal/cauterize wounds where as low level lasers are used to treat injuries and promote healing. Though not designed medical use and not to be used with out medical approval, high power laser pointers and portable lasers and infrared laser pointers do in both theory and practice have medical applications.

Non lethal deterrent

Laser pointers and portable lasers are now commonly used by law enforcement agencies and armed forces around the world as a highly effective method of non lethal deterrent. The beam from these lasers can temporarily overwhelm a hostiles visual senses and cause severe disorientation, effectively neutralizing them without resulting in permanent eye damage or the use of force.

Military applications for laser pointers range from painting targets and directing troop movements to warning potential hostiles. Portable lasers are also used by the military to how to warn/deter suspicious or aggressively driven vehicles that approach checkpoints or convoy operations with out using potentially lethal force.

High power laser pointer has been used by a number of coalition force members in both Iraq and Afghanistan. Being durable, field portable and with a beam that can span the largest battlefield, well built high power laser pointers are ideal for the role of non lethal deterrent.

Experiments

Lasers can provide you with hours of fun conducting experiments that provide insights into light, optics, electronics, energy and lots more. Much more beneficial and enjoyable a boring class room or stale text book.

Experiments can range in complexity from some as simple as popping a balloon (heat conduction and reflectivity) to as complicated as bending light (wave propagation).

Camping/Hiking

Laser pointers and portable lasers are great aids for camping and hiking. There is nothing worse than being stuck out in the middle of the bush during the wind and rain and with wet matches and not being able to light a fire. High powered lasers are great for lighting fires. Lasers with a beam that is visible for miles can also be used to signal for help in the event that you are lost or need aid.

Lasers can also provide adequate illumination at night that unlike a normal torch, will not ruin your night vision. High power laser pointer are so light and small, you can hike with them in your pockets and not even notice the weight. The larger laser portable lasers weigh the same as a small flashlight and can easily fit in your back pack. It's also strong enough to survive the heaviest pounding and roughest trail.

Having Fun

There is nothing like having the coolest high tech gadget with a lethal sky spanning beam to impress your friends. Just imagine the look on their faces when you start popping balloons and lighting matches. Not to mention the attention you'll get when you use your laser outside at night projecting a bright green/red/blue light that goes for miles. High power laser pointers and portable lasers are definitely not toys but they are a lot of fun.

Laser Pointer Pens - Presentation Pointers and Green Laser Pens Gadget Junk

We have all seen our share of laser pointer pens, either being used as presentation pointers or as simple astronomy laser pointers, but unfortunately they are giving lasers a bad name. This is simply because of how poorly crafted most of these laserpens actually are. People looking for precision light instruments are persistently being stuck with shoddy laser diodes that burn out or malfunction long before the beam should die. It seems finding high quality laser pens will require a bit more research to do nowadays.

If you know where to look, the internet can open the door to a plethora of reputable laserpen retailers. Many of these companies carry different laser beam color frequencies (the most popular of which are green laser pens) as well as output powers, so finding a high quality laser pointer pen to meet your particular needs can be easy. However, there are some things you must always look for to determine the quality and value of a laser before you decide to order the device.

First of all, what exactly are you looking to accomplish with your new laser pen? Are you looking for a presentation pointer? Do you need a laser keychain? What color laser beam do you need? How much output power will your application require? These are all simple questions that you need to have an answer to before you go out looking to purchase a laser pointer pen, they will directly effect the cost and availability of any hand held portable laser we are looking for. .

Secondly, what sort of price range or budget are you working with? This will really be very important because you won't always be able to buy laser pointers cheap, especially if there is any kind of decent quality to the device. Low price does not necessarily mean that the laserpen will be a good buy, a lot of cheap lasers have very poor quality diodes which can tend to burn out even after only minimal use. Many presentation lasers have a high price tag because these are advanced pieces of technology and are relatively expensive to produce, lasers are tangible goods where price almost always is directly connected to quality.

If you are looking for something practical and low in power, you can expect the cost of your laser pen to be relatively low. If you are in need of a high power laser pointer or a submergible laser device, you can expect the cost to be a bit higher. Buying quality lasers is really kind of like car shopping, cost will directly effect the amount of accessories or add on's attached to your pointer pen, the only difference is that laser pen providers don't allow for any "test drives". For this reason, you really need to know for sure that the laser pointer pen you are purchasing is the ideal presentation pointer for your application. Green laser pens will typically have the highest available output power, even up to 500mW on certain extreme laser pointers, so be careful and concise when ordering your laser pen.

Because lasers produce condensed light radiation, even the weakest of laser pointer pens has to be used with great care. Even a weak laser beam can cause permanent laser eye damage, so be cautious is a must whenever handling laser devices, especially hand held presentation pointers. They are small lasers and can be used in far more ways than a traditional laser unit, be sure you keep your safety as well as the safety of others in mind. A simple slip of a laserpens beam can be dangerous, so do not take any chances.
