利用由两个长细胞组成的受激布里渊散射（SBS）实现了高压缩比。在重碳FC-40液体中，将13-ns Nd:YAG激光脉冲暂时压缩为约160-ps的相位共轭脉冲，波长为1064nm。SBS工艺的最大反射率超过80%，无光学损伤。压缩后的脉冲亮度约为入射脉冲亮度的65倍。
We have achieved a high compression ratio by stimulated Brillouin scattering (SBS) consisting of two long cells. A 13-ns Nd:YAG laser pulse was temporally compressed to about 160-ps phase-conjugated pulse in heavy fluorocarbon FC-40 liquid at a 1064 nm wavelength. The maximum reflectivity of SBS process was over 80 % without an optical damage. The compressed pulse brightness was about 65-fold higher than that of the incident pulse.
