Laser diode structures typically employ
A laser diode consists of the p-n junction where both electrons and holes are involved. An excess of negatively charged carriers, or electrons, is produced by the n-type area, and an excess of positively charged carriers, or holes, is produced by the p-type. These devices are capable of producing an intense laser ray with uniformly sized light waves. The laser diode principle involves three fundamental processes: absorption, spontaneous emission, and stimulated emission. For laser action, stimulated emission must dominate, requiring population inversion achieved through electrical pumping. The basic device structure consists of a rectangular parallelepiped of a direct bandgap semiconductor, usually a III–V compound semiconductor such as GaAs, incorporat-ing a forward-biased, heavily doped p–n junction to provide the optical gain medium in a resonant optical cavity, as illustrated.

Laser Diode Light Efficiency
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.
