In the past year, we have been able to generate with our Femtolaser V system (800 nm, 5 mJ, 1 kHz, CEP stabilized) high harmonic spectra up to 130 eV pulses in a filament created in a differential pumped gas cell. We plan to extend this region with our TOPAS system. We have already measured CEP (carrier envelope phase) stabilized laser pulses of 2400 nm up to 1mJ. The setup will allow us to extend the HHG cut-off region up to 400 eV.

在过去的一年中，我们已经能够使用 Femtolaser V 系统（800 nm、5 mJ、1 kHz、CEP 稳定）在差动泵气室中创建的灯丝中生成高达 130 eV 的高次谐波光谱。我们计划通过 TOPAS 系统扩展该区域。我们已经测量了 2400 nm 至 1 mJ 的 CEP（载波包络相位）稳定激光脉冲。该装置将使我们能够将 HHG 截止区域扩展至 400 eV。
