摘　　要：以纳秒级调Q倍频的Nd∶YAG激光器为抽运源、以自锁模钛宝石激光器输出并经光栅展宽的 80 0nm啁啾脉冲为信号光 ,实验研究了其宽带BBO I非共线相位匹配光学参变啁啾脉冲放大 (OPCPA)的增益谱。研究结果表明 ,非共线夹角的变化对BBO I非共线相位匹配光学参变啁啾脉冲放大的增益谱有很大的影响。BBO-I noncollinear optical parametric chirped pulse amplifier pumped by a Q-switched and frequency-doubled Nd:YAG laser was studied experimentally. The signal is a chirped pulse at a wavelength of 800 nm, which is obtained from a self-mode-locked Ti:sapphire laser and stretched by a grating pair. The result shows that the variation of noncollinear angle affects the gain spectrum significantly.
