A hundred-watt millijoule-level disk and single-crystal fiber cascade amplifier were demonstrated. We innovatively adopted a disk regeneration amplifier as the front end of the single-crystal fiber amplifier. After single-pass amplification by the single-crystal fiber amplifier, a hundred-watt millijoule picosecond laser output is obtained with an average power of 210.1 W and a pulse energy of 1.05 mJ. To the best of our knowledge, this is the first time that the single-crystal fiber amplifier has achieved both hundred-watt and millijoule simultaneously.
展示了一种百瓦级毫焦耳级的盘片与单晶硅光纤级联放大器。我们创新性地采用盘片再生放大器作为单晶硅光纤放大器的前端。经过单晶硅光纤放大器的单程放大后，获得了百瓦级毫焦耳皮秒激光输出，平均功率为210.1瓦，脉冲能量为1.05毫焦耳。据我们所知，这是单晶硅光纤放大器首次同时实现百瓦级和毫焦耳级。
