How The EPA’s Green Tyranny Is Stifling America

This video explains why Obama's EPA is different and more dangerous than any other since the agency was created. While the tentacles of this EPA are silently creeping into our lives, Lisa Jackson smilingly assures us that everything the EPA does generates revenue -- instead of costing industry billions of dollars and America hundreds of thousands of jobs.

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

3 Tips To Buy Green Lasers Keeping Safety In Mind

The world of laser technology is evolving each and every year and if you're looking to buy green lasers there are a few things you should keep in mind to ensure the quality of any model you choose as well as safety factors for yourself and onlookers. As laser pointers produce a good amount of condensed laser light under specific light frequencies and potentially very high powers, certain models will do a far better job at protecting the user than others.

Here are a few things you should keep in mind whenever looking to buy a green laser or any laser pointer for that matter.

1. FDA Accession Numbers: as more and more lasers hit the open market it becomes overwhelming clear that 99% of them have not been evaluated by the Food and Drug Administration (FDA). This means that they may not only be potentially dangerous by not including certain safety mechanisms, but also that they may not be fully legal to own and operate. As most laser providers are outside of the United States it seems that they either don't care about the laws designed to protect laser users or simply don't know. Either way there is no excuse for selling lasers that are not legal and you should always avoid brands that are not FDA accessioned.

2. Warranty Period: cheaper laser pointers and cheaper manufacturers know that poorly designed laser products tend to burn out and have the diodes fail quite regularly. This means that you can be looking to buy a laser, get it in hand, use it for a bit only to find that it's so poorly designed it actually burns itself out in a short period of time. Any laser company that offers no warranty or a warranty period of less than a year should be put in question thoroughly and not trusted. After all, when you buy green lasers you're making an investment into laser technology and should expect some longevity in the model you choose.

3. Proper Safety Features: cheaper lasers also tend to not incorporate proper safety measures in their design and manufacturing process. Typically this is to keep production cost down but not only does this lead to potentially dangerous models, but also models that tend to fail rather quickly. Most importantly is infrared filters which do not allow the laser itself to emit any of the potentially damaging infrared laser light to be exposed to the human eye. As this light is invisible it is all but impossible to detect without equipment and can cause injury to the retina of users or onlookers.

All in all whenever you're considering buying lasers, especially powerful 532nm green laser pointers, you want to do a fair amount of research into the model and company you're considering. Not all lasers are created equal and neither are manufacturers, not by a long shot. With even just a small amount of research you can ensure that you're going with something that is safe, trustworthy, and that will last a long time.

Jim is an avid laser enthusiast who has written and spoken extensively about the practical applications of lasers in today's world. His preferred source to buy green lasers is the only United States based provider, BigLasers.com, where all lasers are FDA approved.

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.

Danger Zone in Red, Green and Blue Lasers

Some lasers are not the average laser pointers that can be found at any regular electronics store. They can burn dark roles, dark objects, melt plastics, pop balloons, light matches, open bar fragile materials and some can even light cigarettes. Some laser pointers offer power up to 700mW. These lasers are the most powerful in the world and so close to a real life thing to know that there laser.

Pointers with high power laser

In recent years, high power lasers have emerged in the consumer market from the military and specialty applications investigating a series of specialized suppliers. These pointers high power laser can easily exceed several hundred milliseconds-watt output power. They are generally classified as Class IIIb lasers. Although laser enthusiasts still take them as "pointers", true high-power portable lasers - far more capable than the average laser pen key chains (under 5mW) that can be found anywhere.

Green laser pointers

The green lasers are renowned for their small beam diameter and high output power. With the inherent human sensitivity to green, the green laser pointers laser beams creates more powerful and brighter than can be seen anywhere. These beams carry the destructive power so great that almost any object passing through fusible and flammable. They also travel tens and hundreds of miles in the dark. Exceptional power, energy beam of high intensity and super long distance, all these create a pheromone seen only in science fiction movies. Because of these characteristics, these lasers are commonly used by astronomers to study the stars because they usually can visually see the stars coming from the perspective here. It is often also seen in U.S. military operations to disorient and intimidate the enemy, due to its unique beam qualities and highly durable construction.

Because of these features, these lasers are best used by astronomers to study stars for they can often be seen visually reaching the stars from the prospective of a behold. They are often seen in U.S. military operations to disorient and intimidate the enemy as well due to their exceptional qualities and highly durable beam constructions.

Red laser pointers

The red laser pens drive higher output power on red laser pointers. They are exceptionally suitable for burning and offer prices. These red pointer pens can point to a point a hundred miles away and burn, cut and sweep the plastic like their green counterparts. They constantly shed their laser pointer 5mW average over 50x in terms of range, energy to burn and durability.

Blue laser pointers

The blue laser technology is still in its adolescent stage. Since it is very start, is dedicated to developing and marketing this new laser technology and challenging.

Our series is one of the few blue lasers pointer pen with beams more powerful than you can find anywhere in the universe of blue laser.

Green Lasers Incorporate New Technology and Military Capabilities

The latest and greatest in green laser pointer technology have really begun expanding their abilities to provide great lifetime and a number of functions that find themselves practical for every day use, and military use. As opposed to what most people think, green lasers are used by various military forces quite regularly, from training exercises to actual combat excursions the military finds a number of valuable assets in laser pointers.

The newest green laser technology provides some spectacular advancements that the military finds quite formidable. Such as hard shell casings that are actually designed to withstand weapon recoil, water proofing, and the ability to use the laser as a close range blunt force weapon similar to a bayonet. When push comes to shove, there are only a few lasers out there that will meet the strict standards required for military deployment. But if you know where to look you can get your hands on the same lasers designed and used by the US military, completely legally of course, and get the finest laser pointer technology there is.

Now, naturally doing a bit of research into any product you are considering is a good idea, especially when it comes to new lasers. Different manufacturers develop different designs and they can run the gamet from a great laser to a piece of junk, so knowing what to look for or where can be key to getting something worth your time. Also, you should think about what you need the laser for, how far do you plan on aiming the beam, what color are you looking for, etc.

Military lasers are no longer reserved for non-private use and can really provide a great addition to anyone's gadget collection. The technology has become far more accessible and powerful lasers have become reasonably priced as opposed to the large sums required when the technology was first developed over a decade ago. Today you can get a 100mW green laser (about 20+ miles of distance from the beam) for less than $500 which was unheard of some years ago. Depending on what your looking for these can also now be used in convenient pen shaped forms instead of the large bulky designs that used batteries you could never find.

Safety is going to be a key issue whenever considering a green laser that is powerful, really above 50mW. When you start to get towards the higher outputs you may consider safety goggles for protection when using the beam up close, but also where you are aiming the laser. Where as the military is specifically using the lasers to target planes, buildings, and insurgents or people, you are not allowed to. It is illegal to point a laser at an airplane in the United States and rightfully so, it can be a nuisance to a pilot. Although there has never been any cases of accidents being caused by lasers, it is still illegal and never a good idea anyway. So keep some safety in mind when you are using a laser, but besides basic common sense there really is nothing stopping you.

James has been speaking and writing about laser pointer technology and green lasers for more than a decade and has seen the transformations made by leading green laser manufacturers. As an expert in the field with ties to military tech's and leading industry tech's his advice in design and functionality has been used for leading technology trends and positive changes in the past.

DPSS Green Lasers - How Green Laser Pointers Work

Green laser pointers are Diode Pumped Solid State lasers or DPSS lasers for short. As DPSS lasers are more complicated and manufactured with more parts, they are more expensive to produce compared to red laser pointers. Below is a basic rundown of how green light is produced from a 808nm laser diode:

Most green laser pointers are powered by two triple A batteries. The batteries are used to power an infrared 808nm wavelength laser diode.
The 808nm infrared light from the laser diode is used to pump a Neodymium doped Yttrium Orthvanadate or Nd:YVO4 crystal which produces light with a wavelength of 1064nm.
The 1064nm wavelength light is then frequency doubled through a Potassium Titanium Oxide Phosphate (KTiOPO4) or KTP crystal. By doubling the laser frequency, you cut the laser wavelength in half producing a 532nm green laser light.
Generally speaking, DPSS green lasers are approximately 20% - 30% efficient. That is, a green DPSS lasers using a 200mW 808nm pump diode should produce a 40mW to 60mW 532nm green laser pointer. However, as there are various lenses and filters (such as an infrared or IR filter) involved in the process of producing green light, the efficiency level is sometimes less. The efficiency depends on the quality of crystals and lenses used in the laser pointer.

Blue DPSS lasers actually use a similar process. The infrared 808 nm laser diode is used to pump a Neodymium Yttrium Vanadium Oxide or Nd:YVO4 crystal. The outcome is an infrared light with a wavelength of 946nm. This 946nm light is then frequency doubled via a Lanthanum Boron Oxide or LBO crystal to produce a 473nm blue laser. As the efficiency for blue lasers is only around 3%-5%, blue laser pointers are relatively weak in power.

Green Lasers

Lasers that lie in the green spectral region with a wavelength of 510 to 570 nanometers are termed as green lasers. Green laser technology is used in laser pointers, laser projection displays, interferometers, and for pumping of solid-state lasers such as Ti-sapphire lasers. It is also used in processing different types of materials such as copper, gold, or silicon as they have a much higher absorption coefficient as compared to near-infrared lasers.

Green laser usage and performance is limited, as it has a low spectrum range for selecting a laser gain media. However, they are the most commonly used visible lasers due to their uniqueness.

The most common lasers include Argon-ion lasers that are created with the amplification of light in argon plasma formed with an electrical discharge. They are potent light sources for various wavelengths and can achieve highest amount of power at 514 nanometers. Green lasers can easily exceed these limits, but will have to use many kilowatts of electrical power and the corresponding increase in dimensions of cooling systems will be significant. Small air-cooled tubes are used in green lasers that require hundreds of watts of electrical power for generating green laser beams of 10 mille-watts capacity. The tubes are very expensive and have a limited operational life of around a few thousand hours.

Another type of green laser is the Erbium-doped up-conversion laser based on erbium-doped fibers or bulk crystals that can emit around a 550-nanometer good quality laser beam. Frequency-doubled is another technique of creating green laser, in which a frequency doubler is used to convert radiation emitted by a normal laser into green laser. This technique is however very costly and is used only for conducting research work.

Research scientists are working on a number of projects for developing a mechanism that will enable the transmission of electronic data via green lasers. This mechanism, if successfully developed at affordable costs, will change the way people communicate with each other.

Green Laser Pointers And Aircraft

With the increasing popularity of high power green laser pointers, there are more and more reports of lasers being pointed at airplanes and helicopters. In 2008 alone there a number of reports that received wide spread media coverage. One such case in the United Arab Emirates capital of Dubai, two Arab men were charged, tried and convicted with pointing a laser beam at an aircraft during landing.

The exposure of these cases has received has led to a number of misconceptions and misunderstandings on green laser pointers and their danger to aircraft. The purpose of this report is to separate fact from fiction.

Background information on lasers

Very simply laser beams are very concentrated and narrow beams of light and lasers can have a range measured in tens of kilometers. A high power green laser pointer may have a range of 20 to 30 kilometers but it will not have any power or be dangerous at this range. Even the best quality lasers will have a beam that grows in size by 10cm for every 100 meters. By the time the laser beam has covered 1 kilometer, the beam will be the size of a door way and will be incapable of causing any damage or harm.

Green laser pointers not red, blue or orange laser pointers are the main lasers pointed at aircraft because green is much more visible to the human eye than the other colors. The other reason is blue lasers and orange lasers are too expensive and relatively low powered to have wide spread use.

Real and imagined dangers

There are no commercially available and very few if any military lasers that can do physical damage to aircraft. The three main concerns and dangers to a pilot's vision of pointing green laser pointers at aircraft is distraction, causing glare and temporary flash blindness. A fourth concern is eye damage but this is much less likely.

It is highly unlikely that any of these four dangers would result in a loss of aircraft or life. These dangers would only occur when a person deliberately points and tracks an aircraft with a green laser pointer. These dangers also only occur when an aircraft is taking of or landing and the aircraft is at a low enough altitude for a laser to strike the cockpit.

In summary

For the laser hobbyist who does not deliberately target an aircraft, green laser pointers are safe to use out doors at night. A good precaution when pointing lasers at the sky is to first check the sky to make sure it is free of aircraft and avoid using green laser pointers around airports.

For people thinking of pointing green laser pointers, it is Federal offence in the USA and rightly so. Lasers are very easy to track and offenders will face large fines and significant jail time. Pointing lasers at aircraft is also a serious criminal offence in most other countries.

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.

Green Laser Pointers and Laser Guided Weapons

Portable lasers and laser pointers have many applications ranging from avian dispersal and research to laser displays and warfare. One of the more esoteric and less understood applications is guiding bombs and missiles.

The basic idea is a laser pointer will paint or illuminate a target with a laser beam and a laser detector or sensor in the bomb/missile will detect laser light reflected of the target and home on the reflected light. The sensor will detect the strongest source of laser light and steer the weapon to that source using course corrections with its control surfaces (non powered weapons such as free fall bombs) or with motor (rockets).

The advantage of laser guided weapons is that they can strike a target with extreme precision and reduce or eliminate civilian deaths and property damage (collateral damage is the phrase commonly used by the military and politicians). Laser guided weapons are smaller and contain less explosives than their non guided counterparts making them cheaper to produce and allowing aircraft and other launch platforms to carry more of them.

The key element in the use of laser guided weapons is the illumination of the target by laser light. This is normally achieved by one of two ways. A person on the ground near the target will use a laser pointer to illuminate the target or a laser mounted on the weapons platform, be it an aircraft or missile launcher will have a built in laser that will illuminate the target. A classic example of the use of laser weapons is for a reconnaissance group to infiltrate enemy territory and illuminate the target.

Laser guided weapons do have disadvantages. The weapons are only guided when they can detect the laser beam. This means if the beam is blocked by smoke poor weather or dusty conditions, the weapons can not be guided. This greatly limits the use of these weapons in desert wars such as the Iraqi wars.

A common misunderstanding is that a common green laser pointer can be used with these weapons and pity the poor fool who is using one of these lasers when a laser guided bomb is in the air. The lasers use to guide these weapons are infrared (visible lasers will give the user's position away to the enemy) lasers that used a pulsed system that is coded to the sensor on the weapon. The weapon will only home in on a laser source with a matching code. Your trusty green laser pointer will do many things such as create laser displays, carry out research and entertain your friends. It will even land you in jail if you misuse it BUT it will not bring laser guided weapons down on you.

Purchase Green Lasers With No Risk at Any Output Power

Whenever you're looking to purchase green lasers, or really any piece of technology for that matter, its extremely important to do a little bit of research into what you are getting and why. Take a look at a few tips that will not only get you any green laser you're looking for, but how to do it safely and for pretty cheap as well.

Now, since lasers and laser pointers involve some complicated manufacturing that utilizes the combination of crystals and diodes to maximize any lasers potential and color frequency, its important to be sure that the brand or model you are considering is not some shoddy pointer that is going to burn out on you in a weeks time. If you are going to go for it and buy something, make sure you're getting something that is worth your while, something that is built to last.

First of all, what do you need a green laser for in the first place? For use in a business, or to give a presentation, for military or safety use, etc. Its important to think about why you are in need of a laser and what you plan to do with it, even if you're just a hobbyist who loves the advanced technology of the hand held gadgets. So after you've determined what you need the laser for, you can get a good idea of how powerful your green laser should be.

If you are using the beam for short distances, well then you'd probably only need something that isn't too powerful, but if you need the beam to be visible for miles well then you'd want to go with a higher output power.

Second of all, give your brand or model a little 'online inspection', by simply looking at testimonials or stats/specs of the laser itself. See what other people who have the laser are saying about it on the web, and compare prices to find the best deal online for your needs. Remember about the quality of your laser diodes and why its so important. You may have found a powerful green laser at 100mW you want to buy that just doesn't seem right and the price is too low. Lasers are like cars or any other item of varying quality, you can find some real cheap one's but that doesn't mean that its worth your time or money if its just going to burn or blow out on you and stop working in a day or so. What you see is what you get with lasers, the cheaper and poorer quality the manufacturing, the faster the laser is guaranteed to stop working.

Also, what type of warranties are offered on the laser? A reputable laser provider will have manufacturer's warranties as well as add on's you can choose from to protect your investment, because that's what it is, and investment into a gadget, your business, or even hobby. Don't be fooled by the allure of a cheap laser when its just going to die on you, if you're serious about purchasing green lasers, checking the quality or name brand can save you a lot of hassle down the road.

Lastly, since you have thought about what you need a laser for and looked into different brand names and models of green lasers, you are ready to make an educated decision about which type and style of green laser to purchase. Because these are advanced pieces of technology, don't go too cheap as you'll find you end up with a poorly designed and built laser that may not even last a week, but also compare prices online to find the best value for your dollar and needs.

Certain laser providers carry brands that others don't, while some carry everything within the realms of quality and assurance. Look for laser warranties and actual customer service, this can be huge if you ever run into a problem or just have a question about any laser you're considering. The point is, don't be shy in asking questions and make sure that you purchase green lasers from some place reputable, who will ship quickly and provide you with a powerful laser tool that is built to last.

James has written and spoken extensively over the past 2 decades about the importance of lasers in our society and how they will continue to effect our cultures and technology in the future. His preferred place to purchase green lasers is USA based BigLasers.com, the web's #1 provider of such a wide selection of laser models actually worth your time.

Laser Pointers - How You Can Buy a Burning Green Laser and Get it Sent Right to Your Front Door

So by now all of us have just about seen or heard about laser pointers. Now, whether that is in a good way or a bad way depends on who you talk to and the news media.

Most laser pointers are used practically and safely by hobbyists and astronomers or star gazers who love the appeal of green lasers and being able to buy them cheap online (but still high quality). Anyone who has used a green laser pointer with a telescope will tell you, "it's like pinpointing your spot in the galaxy", and with some green beams capable of producing condensed light for more than 50 miles, you can see why laser pointers are appealing.

There is even research being done to fight skin diseases as well as other types of cancers and ailments (including hair removal) using the very same laser pointers you can buy online, and that has people bewildered at the actual therapeutic values and the law of lasers. But the point is that lasers are being used for groundbreaking technology in a number of fields from medicine to architecture to astronomy and so many more, its the greatest light tool and many people even use them for laser presentations with a simple 5mw green laser pointer or an old fashioned red laser (which nowadays can be light light sabers!)

But, despite all of the benefits to research and humanity that laser pointers are providing, there are also people who oppose their use, and this is not unfounded either. There have been cases of people pointing the powerful green laser at an airplane from several points and occasions across the globe. Even using a laser pointer to try and temporarily confuse or distract a goalie in a soccer game in Europe. What's more, many of these powerful lasers are intended for military use and are capable of melting plastic or burning rubber not to mention pinpointing a target more than several miles away, these are no shoddy lasers.

So what is the verdict? Can you buy lasers online and be OK?

The answer.... a resounding YES.

Not only are many FDA approved, these lasers have practical values for just about anyone from teachers to Navy SEALS at war in Afghanistan pinpointing enemies with a powerful green laser or infrared laser when using night vision. The spectrum of people who benefit from a good quality laser is vast, and that should continue to grow as lasers are made more accessible and designs are improved and made more powerful.

The idea is to use common sense whenever using a laser pointer or thinking about buying one. There are a lot of them out there and just like buying a car, name brands and reputations do make a difference. You can do a search and find a million retailers with sales on cheap laser pointers that will break on you within a week, and that's if your lucky. Or you can do the smart thing and put in a few more minutes of research on the web, see who is offering the best lasers out there for the lowest prices online, then you've found yourself a laser pointer worth working with. That's why the web is so great, you can comparison shop anything!

Whatever color laser frequency you feel is the best for you, be it green at 532nm, blue at 473nm, red at 650nm, or even yellow /orange laser pointers, be sure to use them carefully as they do produce light radiation. Green lasers are the brightest to the human eye and are therefore the most popular, make an investment in a good one and it can last you just about a life time.

James has been using laser pointer for over a decade and has successfully developed improved diodes and design suggestions for various laser models that are now still available. He enjoys working with lasers but cannot get anywhere near the power and consistency as the professional resources can provide. His preferred provider of laser pointers is globally trusted http://www.Thinklasers.com who is the only USA based retailer to provide the vast number of green lasers and pointers of all colors and output powers at the the lowest prices online for top quality and brand name lasers.

What is the Difference Between Green and Red Lasers?

This most obvious difference between green and red lasers is the wavelength of the beam. Green lasers have a wavelength between 560nm and 490nm with 532nm being the wavelength used for almost every laser. Some green lasers will have a wavelength of 526.5nm and green lasers can be made with other wavelengths such as 515nm, 523.5nm and 543nm. The wavelength for red lasers ranges from 700nm to 630nm with the most common wavelengths being 635nm, 655nm and 671nm.

The process used to create the laser beam in green lasers is very different from the process in red lasers. Red lasers are the simplest and the laser module (the section producing the beam) is just a diode and a lens. Green lasers on the other hand are much more complex and use a diode and a series of crystals and lens in a process called frequency doubling to produce a green beam.

In a red laser, the laser diode gives out red light. There are no commonly available diodes that give out green light so green lasers use a diode that gives out 808nm light. The 808nm is then converted to 1064nm by a crystal. The 1064nm light is then changed again, this time to 532nm.

The human eye is much more sensitive to green light than red light with estimates on sensitivity ranging from 10 times more sensitive to 50 times more sensitive. The higher sensitivity of the human eye to green means that green lasers are much brighter than red lasers and more suitable than red lasers for many applications such as pointing, alignment and astronomy. Green is normally the color of choice for general purpose lasers with red normally only used for research, laser shows and specific industrial applications.

Colored lasers, often called RGB lasers, are made using a blue laser, a red laser and a green laser. Due to the different brightness of red lasers to green lasers and even blue lasers, different ratios of power are need for red, blue and green are to produce a balanced white light. Using 635nm red light, the common power ratio for the three different colors is 3 red to 2 blue to 1 green.

Green and red laser light have different physical properties which not only effects their application, the different also effects the laser safety glasses that are worn. The laser safety glasses that protect against green laser beams are different from the laser safety glasses that protect against red laser beams. It is critical to the safety of your eyes to make sure that the laser safety glasses you wear match the color of the laser you are using.

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

Green Laser Pointers - A Growing Fad

Green Lasers has always been a mesmerizing feat sensationalized by science fiction from motion picture, Video Games, literature since the 1960s as powerful weapons popularly named as death rays, light saber, blaster, pulse rifles. The laser is also used as a symbolic icon to justify technological advancement and futuristic metaphor to project high technology breakthroughs through the laser.

Looking into the deeper sense of the green laser social effects, a lot of people in the world has embraced the power of the laser beam. The race for making a weapon of destruction from fantasy to reality has endless boundaries and lasers have been dubbed again as a forefront in making futuristic weapons come true.

Lasers and the Youth

The youth of today has found laser science fiction in reality with Green Laser Pointers. Basically used as a presentation pointer, for star gazing and leveling tool. The laser pointer is considered safe to use. However, the laser pointer has also been an opportunity to make death rays and light sabers by using true green laser beams. A regular 5mW laser pointer can emit a bright beam that projects totally the same photonic light as what we see in science fiction. There are laser pointers and handheld lasers that have higher power ratings from 15mW up to 600mW that can emit brighter beams and may be considered lethal and cause permanent eye damage.

A group of laser enthusiasts worldwide modify these lasers and show to fellow enthusiasts how powerful their modified lasers can be by popping balloons to distances as far as 10 feet or lighting matches and cutting plastics with a laser pointer has been a fad to a limited number of aspiring scientists and hobbyists. With the presence of this fad, more and more people are being indulged to the interest of laser pointer modification with a common goal of creating a high powered laser that can cut and burn. It may not be as harmful as it may seem but it is a way to make that death ray a reality by burning or cutting something with a true laser beam.

Other enthusiasts are interested in laser light projection by reflecting laser beams to mirrors and optical convex and concave lenses and perform laser beam art. Thus providing momentary unique light entertainment through laser beams which is also famous in night clubs as a light effect and people get attracted to it.

The laser pointer is creating a new generation of interest in the information age that can be compared to the slinky in the 1940s. This aspect of laser pointer function makes a fad to the youth.

Responsible Use of Green Laser Pointers

The commercial availability of High powered laser pointers has been present since 2004 and merchants warn and constantly remind buyers to be responsible in handling lasers. It is always advised that a high powered laser be used with proper eye protection and pointing to air crafts is a criminal offense. Remember that a laser pointer beyond 5mW is not a toy and requires responsible handling by the owner.
