| 摘 要： | 利用瞬态光栅衍射法研制了一台单次频率分辨光学开关激光参数测量仪，可以对脉宽范围在10 ps以内的紫外超短脉冲激光进行单次测量。利用该仪器对重复频率为10 Hz的放电泵浦和单次运行的电子束泵浦KrF准分子激光器的输出脉冲分别进行了单次测量，结果表明：对于放电泵浦，当系统工作在零啁啾附近时，脉冲波形和光谱分布较规则，相位分布起伏较小，当系统偏离零啁啾状态时，脉冲波形和光谱分布不再规则，并且相位分布为抛物线结构；对于单次运行的电子束泵浦，脉冲波形具有多峰结构，光谱具有复杂的调制，脉宽约为2 ps，带宽约为1.3 nm，相位分布为抛物线结构。

| Abstract: | A single-shot transient-grating frequency-resolved optical gating(TG-FROG) device was set up to measure UV ultrashort pulse laser with pulse duration within 10 ps.The performance of the device was demonstrated by experimental data measured on discharge-pumped KrF laser which is operated in 10 Hz repeated frequency mode,and on electron-beam-pumped KrF laser which is only operated in single-shot mode.For the former,the TG-FROG can distinguish the changes of the pulse shape,spectrum and phase when the pulse ch... |
