OverviewTheoryHistoryTypesReliabilityApplicationsCommon wavelengthsFurther reading
A laser diode (LD, also injection laser diode or ILD or semiconductor laser or diode laser) is a semiconductor device similar to a light-emitting diode in which a diode pumped directly with electrical current can create lasing conditions at the diode''s junction. Driven by voltage, the doped p–n-transition allows for recombination of an electron wit
