摘　　要：利用瞬态包含抽运抽空的SBS理论模型对布里渊放大器进行了数值模拟 ,给出了能量提取效率、Stokes种子光放大率、Stokes种子光脉宽压缩率和抽运光脉宽压缩率随抽运功率密度的变化规律 .并用实验进行了验证 ,理论与实验符合得较好 .Brillouin amplification was numerically simulated by using the theoretical model of transient stimulated Brillouin scattering include pump depletion.Energy extract efficiency, seed amplification factor, pulse-width compression ratios of seed to Stokes and pump to Stokes versus pump power density were given. Experiment was done so as to verify the theory. The theoretical calculations were coincident with experimental results well.
