以自启动被动锁模掺镱光纤堆积脉冲激光器为种子源，采用非共线相位匹配的方法，进行了光参量啁啾脉冲放大器的实验研究，得到了两级放大总增益为1.1×107，单脉冲能量为11 mJ，能量稳定性小于2％ rms，8 nm的放大谱宽.实验结果表明，采用这种结构的光参量啁啾脉冲放大器，放大增益高，系统稳定、结构紧凑、便于调节，同时通过调节种子源中的堆积器，可以得到不同宽度的放大信号脉冲.

A compact,low cost,stable noncollinear optical parametric chirped pulse amplification system is studied,which is seeded by an Yb3+-doped self-starting passive mode-locked stacking pulse fiber laser centered at 1 053 nm.A gain higher than 1.1×107, single pulse energy exceeding 11 mJ with fluctuations less than 2% rms ,8 nm amplified signal spectrum are achieved.Different pulse durations of amplified signal are obtained by adjusting the stacker of the Yb3+-doped self-starting passive mode-locked stacking pulse fiber laser.
