The gain fiber of a high-power laser is a gain medium that generates photons. The pump source is used as external energy to make the gain medium to achieve population inversion. The optical resonant cavity is composed of two mirrors. The function is to make the photons get feedback and work. Enlarged in the medium. The pump source enters the gain fiber and is absorbed, which in turn reverses the number of energy level particles in the gain medium. When the gain in the resonant cavity is higher than the loss, a laser oscillation will be formed between the two mirrors to generate laser output. High-power semiconductor laser pointers have broad application prospects in laser pumping sources, laser processing, laser weapons, etc., and have become important basic components and core supporting technologies for national economic and national defense construction.
