We demonstrate a hybrid dual-stage nonlinear compression scheme, which allows the temporal compression of 330 fs-pulses down to 6.8 fs-pulses, with an overall transmission of 61%. This high transmission is obtained by using a first compression stage based on a gas-filled multipass cell, and a second stage based on a large-core gas-filled capillary. The source output is fully characterized in terms of spectral, temporal, spatial, and short- and long-term stability properties. The system's compactness, stability, and high average power makes it ideally suited to drive high photon flux XUV sources through high harmonic generation.
我们展示了一种混合双阶段非线性压缩方案，该方案可将330飞秒脉冲在时间上压缩至6.8飞秒脉冲，总传输率为61%。这种高传输率是通过使用基于充气多程池的第一压缩阶段和基于大芯充气毛细管的第二阶段实现的。源输出在光谱、时间、空间以及短期和长期稳定性特性方面得到了全面表征。该系统的紧凑性、稳定性和高平均功率使其非常适合通过高次谐波产生来驱动高光子通量极紫外光源。
