semiconductor laser

A solid-state device that consists of two outer semiconductor layers separated by a middle layer and generates laser radiation when charge carriers of opposite polarity, one each from the top and bottom layers, meet in the middle layer. Also called diode laser.

semiconductor laser

A solid-state laser constructed like a semiconductor diode. At the junction of anode and cathode, electrons and holes come together; when an electron falls into a hole, bandgap radiation is emitted, as in a light emitting diode. Semiconductor lasers are constructed so that the resulting light tends to stimulate other nearby pairs of electrons and holes to undergo the same process, emitting more light. Also called diode laser, laser diode. See more at laser.

bandgap diode laser gallium arsenide laser diode laser tuning LED			The material composition in a traditional semiconductor laser determines the energy wavelength that is produced. The promise of the world's smallest lasers by Jean, Grace V. / National Defense It also explores new fields of research that include surface plasmonics and micro-ring resonators and the theory of optical gain and absorption in quantum dots and quantum wires and their uses in semiconductor lasers. Physics of photonic devices, 2d ed by SciTech Book News After dedicating considerable effort to understanding the dynamics of these injected charge carriers, Bhattacharya was ultimately able to use quantum dots to create a new type of laser that combined the best qualities from semiconductor lasers and atomic lasers.
