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

An Introduction to Laser Diodes

What''s A Laser diode?ApplicationsLaser Diode Drive CircuitryImportant Laser Diode SpecificationsSummaryA laser diode is a semiconductor laser device that is very similar, in both form and operation, to a light-emitting diode (LED). The term laser originated as an acronym: Light Amplification by Stimulated Emission of Radiation. Hence, a laser is a device that emits light through a process of optical amplification based on the stimulated emissions of...See more on allaboutcircuits Thorlabs
