RESEARCH ON THE HIGH POWER LASER OUTPUT USING STIMULATED BRILLION SCATTERING PULSE COMPRESSION

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.
