Background

A laser diode: laser diodes are one of the most commonly used lasers at present, and a phenomenon in which electrons and holes spontaneously recombine to emit light at both sides of a PN junction of the diode is called spontaneous emission. When photons generated by spontaneous emission pass through a semiconductor, the photons, once passing near an emitted electron-hole pair, can stimulate the recombination of the two to generate new photons, and the photons induce the recombination of the excited carriers to emit new photons, which is called stimulated emission. If the injection current is sufficiently large, a carrier distribution opposite to the thermal equilibrium state, i.e., population inversion, is formed. When the current carriers in the active layer are in a large number of inversions, a small number of photons generated by spontaneous radiation are reflected back and forth at two end faces of the resonant cavity to generate induction radiation, so that frequency-selective resonance positive feedback is caused, or gain is provided for a certain frequency. When the gain is larger than the absorption loss, coherent light, laser, with good spectral lines can be emitted from the PN junction. The invention of the laser diode can rapidly popularize the laser application, and various applications such as information scanning, optical fiber communication, laser ranging, laser radar, laser record, laser indicator, supermarket collection and the like are continuously developed and popularized.
