What it is Filled
A device that emits a coherent, narrow and often intense beam of light through stimulated emission of radiation in a gain medium within an optical cavity, in forms such as gas, solid-state, fibre and semiconductor laser diodes, used in communications, medicine including dental lasers, manufacturing, surveying with airborne laser scanners, entertainment, scientific research and, at a public reference level, in high-energy laser weapons such as the Tactical High Energy Laser; lasers are classified by hazard and regulated for eye safety.
