Rare earth ion fiber laser has the characteristics of compact structure and excellent beam quality. Cladding pumped fiber laser has become the best choice to obtain high-power laser. This paper introduces the characteristics of Er/Yb Co doped fiber laser, The theoretical model of Er/Yb Co doped fiber laser is established from the atomic energy level and energy transfer in erbium ytterbium Co doped fiber. By changing the initial pumping conditions and the reflectivity of the rear grating, the output power of the laser with different pumping power and different output mirror reflectivity can be calculated and numerically simulated. In this paper, the theoretical model of Er/Yb Co doped fiber laser is established, the numerical simulation is carried out, and the gain characteristics of the laser are analyzed.
