Category: Laser Diodes

A laser diode 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 with a hole.
