摘要
在Nd∶YAG振-放系统上采用受激布里渊散射后向放大方法补偿了放大器造成的波前畸变,实现了双程放大,从而改善了光束质量.获得重复频率为10Hz,SBS反射率达到70%,SBS后向放大倍数为2.5倍的光强空间分布均匀的稳定输出.
Abstract
By using the SBS PCM, a double way amplified beam with improved beam quality was obtained. The obtained laser frequency is 10 Hz, SBS reflectivity is 70%, and the amplifying coefficient of back SBS is 2.5, as well as a stable output with symmetric distribution was got.
