i think its just a concentrated beam of light
They made lasers to defend the world from space aliens!!!
Certain astronomical phenomena are believed to be a result of the operation of natural lasers. If you mean man-made lasers: sure there are, on satellites and whatnot.
gas lasers: helium-neon, argon, carbon dioxide, nitrogen, etc.liquid lasers: dye, chemical reaction lasers, etc.solid lasers: ruby, semiconductor laser diodes, etc.Lasers can be made many ways. Too many for me to list here.

Semiconductor lasers are made with laser diodes, with added circuitry to measure and regulate the diode current/output.
How do lasers work
lasers damage call composition
Cold lasers are safer and deal less pain than hot lasers. Cold lasers are usually used for repairing skin damage and treating pain and inflammation. Hot lasers are simply used for burning things.
Since the early 1970s Erchonia lasers have been classified by wavelength and maximum output powers into four classes. The lasers are used in treatment of neck and shoulder pain, breast augmentation, acne, laser assisted body augmentation. The types of lasers they use for these treatments include 3LT Lasers, Custom Design Lasers and Zerona Lasers.
the plural of laser is lasers. for example I have many lasers. you don't say I have many laser.
