摘　　要：设计了灯抽运Cr∶LiSAF(Cr∶LiSrAlF6)飞秒再生放大系统 ,对 80fs光脉冲 (展宽后约 10 3ps)进行了再生放大研究 ,获得了再生放大的输出能量与输入能量和放大倍率与放大往返次数间的关系 ,得到了 8× 10 5的放大倍率和 0In this paper, a flashlamp pumped Cr∶LiSAF (Cr∶LiSrAlF 6) regenerative amplifier was developed to amplify chirped light pulses which were stretched from 80 fs to 103 ps. The relation between the amplified output energy and the input energy and that between the net gain and the round-trip number of the chirped pulses in the cavity were determined. Using the regenerative amplifier, a net gain of 8×10 5 and the maximum output pulse energy of 0.4 mJ were obtained.
