Preferred Label : laser;
IUPAC definition : A source of ultraviolet, visible, or infrared radiation which produces light amplification
by stimulated emission of radiation from which the acronym is derived. The light emitted
is coherent except for superradiance emission. The essential elements of a laser are:
1, an active medium; 2, a pumping process to make a population inversion; and 3, suitable
geometry of optical feedback elements. The active medium consists of a host material
(gas, liquid or solid) containing an active species.;
