色散泵浦对受激布里渊散射反射率的影响

Effect of dispersive pump on reflectivity of stimulated Brillouin scattering

摘要: 将宽带KrF激光通过棱镜进行色散,在气压约为2×106Pa的SF6介质中进行受激布里渊散射的实验研究.通过与没有经过色散的KrF激光进行对比,得到经过色散后的KrF激光作为泵浦光比没有经过棱镜色散的KrF激光作为泵浦光产生SBS的反射率高.

Abstract: Experimental investigation of stimulated Birllouin scattering(SBS) in SF6 gas of 2×106Pa has been made with a broadband KrF laser dispersed by a prism.The results show that SBS reflectivity with dispersive KrF laser used as the pump laser is higher than that with KrF laser directly used as the pump laser.
