In this Letter we report on the generation of 830 W compressed average power from a femtosecond fiber chirped pulse amplification (CPA) system. In the high-power operation we achieved a compressor throughput of about 90% by using high-efficiency dielectric gratings. The output pulse duration of 640 fs at 78 MHz repetition rate results in a peak power of 12 MW. Additionally, we discuss further a scaling potential toward and beyond the kilowatt level by overcoming the current scaling limitations imposed by the transversal spatial hole burning.
在这封信件中，我们报告了从飞秒光纤啁啾脉冲放大（CPA）系统中产生 830 W 平均功率压缩的情况。在高功率运行中，我们通过使用高效率介电光栅实现了约 90%的压缩器透过率。在 78 MHz 重复率下，输出脉冲持续时间为 640 fs，峰值功率为 12 MW。此外，我们还通过克服当前由横向空间烧孔引起的限制，进一步讨论了实现千瓦级以上的扩展潜力。
