A source of @UT07492@, @VT07496@, or @IT07399@ radiation which produces light amplification by @S06015@ of radiation from which the acronym is derived. The light emitted is coherent except for @S06145@ emission. The essential elements of a laser are: 1, an @A00106@; 2, a pumping process to make a @P04759@; and 3, suitable geometry of optical feedback elements. The @A00106@ consists of a host material (gas, liquid or solid) containing an @A00110@.
