种子光与抽运光能量比对布里渊放大的影响

The influence of the ratio of seed to pump energy on Brillouin amplification

利用瞬态包含抽运抽空的受激布里渊散射理论模型对布里渊放大器进行了数值模拟 ,给出了布里渊放大器中能量提取效率、种子光放大率、种子光脉宽压缩率和抽运光脉宽压缩率随Stokes种子光与抽运光能量比的变化规律 ,并用实验进行了验证 。

Brillouin amplifier was numerically simulated by using the theoretic model of transient stimulated Brillouin scattering. We have oblained the depleted pump energy extract efficiency, Stokes seed amplification factor, seed beam pulse-width compression ratio and pump beam pulse-width compression ratio versus the ratio of seed to pump energy. Experiment was done so as to verify the theory. The theoretical calculation was in good agreement with experimental results.
