Semiconductor Laser - an overview | ScienceDirect Topics
Semiconductor lasers are the most important tool for (i) direct application to surface heating and welding and (ii) pumping solid-state lasers. One example of semiconductor laser is diode laser, which is currently the most efficient device for converting electrical energy into optical energy.
Laser diode - Wikipedia
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.
Semiconductor laser theory - Wikipedia
Semiconductor lasers or laser diodes play an important part in our everyday lives by providing cheap and compact-size lasers. They consist of complex multi-layer structures requiring nanometer scale accuracy and an elaborate design.

Semiconductor Lasers – laser diodes - RP Photonics
Semiconductor lasers are solid-state lasers based on semiconductor gain media, where optical amplification is usually achieved by stimulated emission at an interband transition under conditions of a high carrier density in the conduction band.
Semiconductor Lasers: An Overview of Commercial Devices
There are two major commercial families of semiconductor lasers — those grown on GaAs substrates and those grown on InP substrates. GaAs-based lasers are formed from alloys of Ga, Al, In and As, P, grown in compositions lattice-matched to GaAs.
How semiconductor laser diodes work - Explain that Stuff
2023年7月26日 · Known as semiconductor lasers (also called diode lasers or injection lasers), they were developed in the early 1960s by Robert N. Hall and, largely because they're so compact and inexpensive, are now the most widespread lasers …
