在充气多程腔中对能量为数十毫焦耳的激光脉冲进行非线性压缩是实现新一代高平均功率飞秒源的一种很有前途的方法。第一次，就我们所知，我们在充满Ar的Herriott池中展示了能量约为18mJ的脉冲在5 kHz重复频率下的非线性展宽，并显示了从1.3ps到41ps的可压缩性。除了具有较大的压缩系数外，输出光束还具有优异的质量和良好的光谱均匀性。此外，我们还讨论了在不久的将来将能量刻度到100MJ水平的前景。(C)2018年美国光学学会
Nonlinear compression of laser pulses with tens of millijoule energy in a gas-filled multipass cell is a promising approach to realize a new generation of high average power femtosecond sources. For the first time, to the best of our knowledge, we demonstrate nonlinear broadening of pulses with about 18 mJ of energy at a 5 kHz repetition rate in an argon-filled Herriott cell and show compressibility from 1.3 ps to 41 fs. In addition to the large compression factor, the output beam has an outstanding quality and excellent spectral homogeneity. Furthermore, we discuss prospects to scale the energy to the 100 mJ level in the near future. (C) 2018 Optical Society of America
