摘要
讨论了利用受激布里渊散射效应实现高功率激光脉冲压缩的基本原理，并做了相应的数值摸拟计算。利用星光Ⅱ装置进行了脉冲压缩的原理性实验，获得了约６０％的能量转换效率和近４倍的压缩比。
Abstract In this paper, the basic principle of how to obtain high power laser output using Stimulated Brillion Scattering (SBS) pulse compression is discussed, and a corresponding numerical simulation is also given. A principle experiment on pulse compression has been done at the φ 40mm output stage of “Xingguang Ⅱ” laser facility, 60% SBS energy conversion efficiency are obtained with 4 times compression ratio (3.2ns/0.8ns). The pulse duration is compressed nearly to the compression limit, with a good stability.
