摘要

介绍了一种新型的高能量环形长腔再生放大器, 通过对谐振腔的模式分布进行计算, 建立了腔长为12 m的环形腔再生放大器, 在150 mJ的抽运能量下, 得到了单脉冲能量为20 mJ的放大激光输出, 对应的转化效率为13.3%, 其输出激光的能量远远超过了常规的再生放大器输出激光的单脉冲量. 放大激光的输出光谱为30 nm, 可以支持<40 fs的傅里叶转换极限脉宽.

We demonstrate a novel regenerative amplifier with a long ring cavity. Calculation on cavity parameters supports a large mode size. Based on the simulation with the cavity design software, we successfully established a 12 m ring regenerative amplifier. The amplified laser energy up to 20 mJ was obtained under 150 mJ green pump laser at a repetition rate of 10 Hz, corresponding to 13.3% conversion efficiency. The spectral bandwidth of the output pulse was 30 nm, which could support a sub 30 fs pulse duration. After seed injection, the ASE of the amplifier was effectively suppressed.
