聚焦泵浦条件对受激布里渊散射反射率影响的理论分析
Theoretical Study of the Effect of Focal Pumping Conditions on Stimulated Brillouin Scattering Reflectivity
【摘要】 理论分析了聚焦泵浦条件对受激布里渊散射反射率的影响,获得反射率与透镜焦点位置、透镜焦距及泵浦光束半径的关系;受激布里渊散射阈值与透镜焦距的关系。理论与实验结果基本上一致。
【Abstract】 The effect of focal pumping conditions on stimulated Brillouin scattering reflectivity is studied theoretically. The dependences of stimulated Brillouin Scattering reflectivity on lens focal length,lens focal point location and pump beam radius are obtained when the dependence of stimulated Brillouin scattering threshld on lens focal length is obtained. The theoretical results are consistent with experimental results qualitatively.
