A laser diode is electrically a PIN diode. The active region of the laser diode is in the intrinsic (I) region, and the carriers (electrons and holes) are pumped into that region from the N and P regions respectively. While initial diode laser research was conducted on simple P–N diodes, all modern lasers use the double-hetero-structure implementation, where the carriers and the photons are confined in order to maximiz
Laser Diodes: Definition, Types, and Applications
A laser diode is a semiconductor device that emits coherent light via stimulated emission, which is more complex and responsive than a light-emitting diode (LED).
