We demonstrate a versatile femtosecond power amplifier using a Yb:YAG single crystal fiber operating from 10 kHz to 10 MHz. For a total pump power of 75 W, up to 30 W is generated from the double-pass power amplifier. At a repetition rate of 10 kHz, an output energy of 1 mJ is obtained after recompression. In this configuration, the pulse duration is 380 fs, corresponding to a peak power of 2.2 GW. The M2 beam quality factor is better than 1.1 for investigated parameters.
我们展示了一种使用 Yb:YAG 单晶光纤的多功能飞秒功率放大器,其工作频率范围从 10 kHz 到 10 MHz。在总泵浦功率为 75 W 的情况下,双通功率放大器可产生高达 30 W 的功率。在重复频率为 10 kHz 的情况下,经再压缩后可获得 1 mJ 的输出能量。在此配置中,脉冲持续时间为 380 fs,对应于 2.2 GW 的峰值功率。对于研究的参数,光束质量 M2 因子优于 1.1。
