摘　　要：实验研究了在不同的Stokes种子光与抽运光能量比条件下 ,布里渊放大池中能量提取效率、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种子与抽运光交角的变化规律 ,在种子光与抽运光的夹角为 1～ 2mrad时 ,提取效率、种子光放大率、种子光脉宽压缩和抽运光脉宽压缩率变化很小 ,Stokes种子光与抽运光有 1～Energy extraction efficiency, seed amplification factor, seed beam pulse width compression ratio and pump beam pulse width compression ratio versus angle between seed and pump beam at different energy ratio of seed to pump were experimentally investigated. When the angle between seed and pump was 1～2 mrad, energy extraction efficiency, seed amplification factor, seed pulse width compression ratio and pump pulse width compression ratio were changed very small. Stokes seed and pump beam could be misaligned by 1～2 mrad.
