A laser beam used for welding red (660 & 635 nm), green (532 & 520 nm) and blue-violet (445 & 405 nm) lasers a laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. the term "laser" originated as an acronym for " light amplification by stimulated emission of radiation ". the first laser was built in 1960 by. Lasers are used in practically every major industry, from medicine and computers to entertainment and construction. a power rating, usually in watts, determines the strength of the laser.some can cut through metal, while others read tiny bits of information without damaging the surface.. Laser, a device that stimulates atoms or molecules to emit light at particular wavelengths and amplifies that light, typically producing a very narrow beam of radiation.the emission generally covers an extremely limited range of visible, infrared, or ultraviolet wavelengths. many different types of lasers have been developed, with highly varied characteristics..
