推导了描述调频激光受激布里渊散射的耦合波方程和准静态近似下增益因子的表达式,分析了啁啾脉冲的散射过程,讨论了泵浦激光和斯托克斯信号光频率调制方式、带宽对泵浦光能量抽取效率和斯托克斯光脉冲波形的影响。

The Stimulated Brillouin Scattering of chirped pulse has been studied theovetically.The coupled equations and gain factor of chirped pulse are derived under quasi-steady state approximation. The affection to the depletion efficiency of pump and the shape of Stokes pulse are discussed under different way of frequency modulation,and the influence of the bandwidth on the depletion of pump is researched.
