High power laser pointers are becoming more and more popular for use in presentations, astronomy and other applications. While they are amazing gadgets to own due to their bright laser beams and capability to burn, high power laser pointers and portable lasers can be potentially dangerous if handled incorrectly. It is important to read and practice the precautions listed below.
What makes the light from lasers so dangerous?
Lasers are coherent and focused. That is, the photons in the laser beam are uni-directional with energy focused on a very small dot. This is similar to the way a magnifying glass focuses the sun energy.
Lasers are collimated. The light does not spread out from a laser like a flashlight. It stays in a focused narrow beam making lasers as dangerous up close as it is at a distance.
Laser Safety Guidelines:
Never point your laser pointer at another person.
Never look directly into the laser beam. Even a low powered laser can be potentially dangerous, do not take chances with your eyes.
Be aware of reflective surfaces such as mirrors, polished metal or glass. A reflected beam can also be potentially dangerous to your eyes.
Use a laser in a controlled environment only. That is, do not shine a laser out your window, there maybe someone walking by.
If you decide to let a friend use your laser, make sure they are fully aware of the dangers of lasers.
Lasers can travel for miles, never randomly use your laser outside.
Wear laser safety glasses at all times.
If you adhere to these guidelines and exercise simple common sense and care, you will be able enjoy and use your high power lasers in complete safety.
