[0002] A semiconductor laser, also known as a laser diode, is a type of laser that uses semiconductor materials as the working medium. Its operating principle is based on the special properties of semiconductor materials. Through excitation methods such as electrical injection, electron beam excitation, or optical pumping, it achieves a population inversion of non-equilibrium carriers between the energy bands of the semiconductor or between the energy bands and impurity energy levels, thereby generating stimulated emission and forming a laser. Semiconductor lasers have the advantages of small size, high efficiency, and low power consumption. They are widely used in communications, medical treatment, material processing, fiber optic sensing and other fields. In particular, double heterojunction lasers and stripe-type laser diodes have a wide range of applications in fiber optic communications, optical discs, laser printers, etc. In addition, semiconductor laser packaging technologies such as TO, COB, DIP, SMD, etc. also ensure their normal operation and improve reliability.
