Considering the influence of stimulated Brillouin scattering (SBS) and the output fiber,a fiber amplifier model is established,and it can effectively describe the amplification of low-frequency pulse. The simulation results show that SBS in fiber amplifier can be effectively suppressed through optimizing length of the doped fiber,cutting down length of the output fiber and increasing peak power of input pulse. The research results can be applied to the design of the single-frequency amplification system.
