  1. The working principle and characteristics of semiconductor laser The working principle of a semiconductor laser is an excitation method. The use of semiconductor materials, that is, the use of electrons to transition between energy bands to emit light. The cleavage plane of the semiconductor crystal is used to form two parallel mirror surfaces as mirrors to form a resonant cavity, which amplifies the light oscillation, feedback, and the generated light, and outputs the laser. The advantages of semiconductor lasers are small size, light weight, reliable operation, low power consumption, and h
