摘要
利用聚焦的后向拉曼过程实现高功率准分子激光的高效脉冲压缩。获得了 1 5倍的脉冲压缩和 1 7%的总体能量转换效率 ,在 1 0J抽运能量下最大获得 1 7J的压缩脉冲输出。
A high efficient backward stimulated Raman compression is obtained pumped by high power KrF laser using focused-beam geometry. The pulse duration is compressed by 15 times with total energy conversion efficiency 17%. Maximum 1.7 J pulse (1.5 ns) is obtained when pumped by 10 J pulse (22 ns). The mechanism of high efficient backward SRS in focused geometry is discussed.
