| 摘 要： | 给出了光学玻璃材料在强泵浦光作用下由光弹耦合激发超声波的瞬态受激布里渊散射理论模型，通过几个合理的近似利用数值计算给出该过程激发的超声波强度对泵浦光强度以及脉宽的依赖关系，计算表明光泵浦光强度超过一定阈值后该超声波能引起光学材料的破坏。

| Abstract: | A theory of the excitation of ultrasound waves arised from photoelastic coupling with high intensity light is presented in this paper.By use of several reasonable approximations, a numerical calculation of the transient stimulated Brillouin scattering (SBS) process shows that a large amplitude of acoustic wave can be built up during the pulse of pump light, and which may result in damage to optical materials. |
