Laser |
Acronym for light amplification by stimulated emission
of radiation. The laser produces a coherent source of
light with a narrow beam and a narrow spectral bandwidth
(about 2cm). Lasers in fiber optics are usually
solid-state semiconductor types. Lasers are used to
provide the high-powered, tightly controlled light wavelengths
necessary for high-speed, long-distance optical
fiber transmissions.
