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 work when electron-hole recombination takes place inside a p-n junction, resulting in the stimulated emission in an optical cavity. This cycle helps in producing the laser light,
