Diode lasers, also known as semiconductor lasers, operate by applying an electrical current to a semiconductor p-n junction, which stimulates the emission of coherent photons through stimulated emission. Unlike LEDs, which emit light randomly, diode lasers integrate an optical resonator formed by reflective facets, allowing photons to bounce back and forth, amplifying light in a single phase, direction, and wavelength. This produces a highly directional, monochromatic, and coherent beam. The wavelength of the emitted light depends on the semiconductor material, ranging from ultraviolet (UV) to far-infrared (IR) .

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
