Abstract

This paper reports on nonlinear spectral broadening of 1.1 ps pulses in a gas-filled multi-pass cell to generate sub-100 fs optical pulses at 1030 nm and 515 nm at pulse energies of 0.8 mJ and 225 µJ, respectively, for pump-probe experiments at the free-electron laser FLASH. Combining a 100 kHz Yb:YAG laser with 180 W in-burst average power and a post-compression platform enables reaching simultaneously high average powers and short pulse durations for high-repetition-rate FEL pump-probe experiments.

摘要

本文报道了在充气多程池中对1.1皮秒脉冲进行非线性光谱展宽，以分别在1030纳米和515纳米处产生亚100飞秒光脉冲，脉冲能量分别为0.8毫焦和225微焦，用于在自由电子激光FLASH上进行泵浦-探测实验。将具有180瓦突发平均功率的100千赫兹Yb:YAG激光器与后压缩平台相结合，能够在高重复率FEL泵浦-探测实验中同时实现高平均功率和短脉冲持续时间。
