| 摘 要： | 分析了准分子激光脉冲在放大过程中的展宽现象。将饱和开关技术应用于放电泵浦激光器放大腔的放大压缩，发展了脉冲负反馈饱和压缩技术。利用该技术在天光一号系统前端LPX-150激光器上成功获得能量100 mJ、脉宽10 ns的脉冲输出，其空间分布均匀性保持在3%以内。这证明该技术可与无阶梯诱导非相干技术联合使用，在保证光束均匀性基础上进行脉冲压缩。

| Abstract: | Theoretical analyses have been done on the cross correlation between pulses of the femtosecond laser sequence. Experimental results are also derived using a cross-correlation setup, which can be switched between intensity cross-correlation mode and interferometric cross-correlation mode. The results show that the pattern of adjacent pulses cross-correlation is similar to that of auto-correlation. In the future, the method can be used in advanced light sources based electron accelerators to stabilize signals and to locate the cavity mirror precisely. |
