Abstract- A high power Ytterbium-doped fiber laser is simulated in this paper. Its pump and output wavelength is 915nm and 1064nm, correspondingly. The output power characteristics of the linear cavity fiber laser have been studied theoretically by solving the rate equations. The optimum length of the fiber and laser efficiency for forward and backward pumpings are obtained 40m, 60% and 62.4%, correspondingly. Also, the threshold powers of stimulated Brillouin scattering are determined for forward pumping, 866.8 W, and backward pumping, 1089 W. Finally, dependence of Brillouin threshold power to laser linewidth is determined.
Keywords: Double-clad fiber, Stimulated Brillouin scattering, Ytterbium fiber laser
