摘要

我们通过结合几个周期、载波包络相位稳定的4µm驱动激光脉冲和一个单周期、400 nm脉冲，对氦气电池中的高谐波产生进行了详细的宏观模拟，证明了双色激光配置与单色方案相比，在1.05-1.25 keV光子能量范围内显著提高了谐波产生效率。此外，我们还证明了通过相位匹配和双色波形控制相结合的方法可以成功地产生分离的keV阿秒脉冲。

Attosecond X-ray pulse generation by waveform control of mid-infrared laser.

We perform detailed macroscopic simulations of high harmonic generation in a He gas cell by combining a few-cycle, carrier-envelope-phase-stabilized 4-µm driving laser pulse with a single-cycle, 400-nm pulse, demonstrating that the two-color laser configuration significantly boosts harmonic generation efficiency in the 1.05-1.25 keV photon-energy range compared to a single-color scheme. Additionally, we show that isolated keV attosecond pulses can be successfully produced through the combined approach of phase matching and two-color waveform control.
