摘要
搭建了一套声光锁模为主振荡器,氙灯抽运的再生放大系统。通过光路设计和精确的时间控制,将脉冲单选模块集成到再生放大腔中。在工作频率20 Hz时,再生放大器输出单脉冲能量≥3.2 mJ,能量放大倍数≥3×104,脉冲宽度305 ps,单脉冲输出100%,光束质量近衍射限。
In this paper, the function of the usual pulse picker was integrated into the stage of regenerative amplifier by the optical configuration design and the precise control of time. Using the improved regenerative amplifier,the output pulse energy of 3.2 mJ is obtained, which the net gains over 3 × 10^4 at 20 Hz repetition rate with 305 ps of pulse duration, and its beam quality near the limited.
