A source of @[email protected], @[email protected], or @[email protected] radiation which produces light amplification by @[email protected] of radiation from which the acronym is derived. The light emitted is coherent except for @[email protected] emission. The essential elements of a laser are: 1, an @[email protected]; 2, a pumping process to make a @[email protected]; and 3, suitable geometry of optical feedback elements. The @[email protected] consists of a host material (gas, liquid or solid) containing an @[email protected]
