摘要：
The influence of forward Raman amplification on Brillouin scattering signal of pulse light was investigated in experiments, including the spontaneous Brillouin scattering and the stimulated Brillouin scattering (SBS). The results of experiments show that the spontaneous Brillouin scattering is amplified by fiber Raman amplifier and fiber Brillouin amplifier, consequently the gain is high. For the amplification of SBS signal, it is only amplified by Raman amplifier in the fiber. As the Raman pump power reaches 600mW, it causes multi-order Brillouin scattering, and then the gain of the first order Stokes SBS starts to saturate and decline.
