本文介绍一种用Nd:YAG双锁模的倍频脉冲序列,同步泵浦以曲率半径R=2m的凹面光栅所组成的染料激光器,实现了高功率可调谐的微微秒染料激光输出。用条纹照相机对同步泵浦锁模激光系统中各部分的输出特性进行了实验研究和测试。

The paper reports the study of synchronous mode-looking of dye laser which hag a hemispherical resonator with a diffraction grating of E = 2M radius of curvature and is pumped by the second-harmonic pulse train from an actively passively mode-locked repetitive pulsed Nd: YAG laser. A broadly tunable, high-power mode-locked dye laser source has been achieved. Beal-time experimental investigation was made of some relationship governing the output characteristics of the dye laser with a BWS-5K high resolution streak camera. Brief analysis and discussion are given concerning the experimental results.
