利用脉冲波面倾斜技术补偿三波相互作用的群速度失配，建立了掺钛蓝宝石飞秒再生放大器输出倍频光泵浦共线类匹配BBO晶体的光参量产生和放大器，其信号和空闲光输出调谐范围为0.47～2.7μｍ，脉冲宽度为100～170 fs，重复率为1 kHz。脉冲最大输出能量为6.5 μＪ，总能量转换效率大于15%。

Compensating for the group velocity mismatch in optical parametric interaction with tilted pumping pulse fronts, an efficient femtosecond collinear type Ⅰ phase matched β barium borate optical parametric generator and amplifier pumped by a tilted second harmonic pulses of the Ti sapphire regenerative amplifier is demonstrated. The signal and idler outputs are tunable from 470 nm to 2.7 μm having pulse widths in the range of 100 to 170 fs at 1 kHz repetition rate. A maximum output energy of 6.5 μJ/pulse and a total conversion efficiency of more than 15% are achieved.
