摘要：With the rapid development of optical communication network and related technology, the frequency resource of light wave is becoming more and more insufficient, which requires new light sources to support the communication system.With the continuous development of fiber laser technology, Tm-doped fiber laser appears, which brings new vitality to the optical communication network with insufficient frequency resources. Because Tm -doped fiber laser can provide multiple frequencies of optical wavelength resources, it has attracted more and more attention. The development of rare earth doping technology and double cladding pumping technology has laid a solid foundation for the design of Tm-doped fiber laser with excellent performance. In this paper, the Tm-doped fiber laser is studied. The effect of each element in the Tm-doped fiber laser on the laser is analyzed. The influence of the reflectivity of the mirror on the performance of the whole laser is discussed. The simulation results show that the reflectivity of the mirror will seriously affect the output power of the laser, which is of great significance for the design of fiber lasers. ?
