Abstract
LASER (light amplification by stimulated emission of radiation) devices transform light of various frequencies into chromatic radiation that is capable of mobilizing heat and power when focused at a close range. They are usually named after the active medium employed, which can either be a container of gas, a crystal, or a solid-state semi conductor.
Key words: LASER, light, radiation, semi conductor.
