论文摘要
NE的两个XUV-PHOTON双电离是由一条强烈的几个pulse Attosecond Train诱导的，具有〜4 FS包膜持续时间，从实验和理论上研究了。该实验是利用最近构建的10 Hz气相高阶谐波生成Sylos GHHG-Compact光束线进行的。与XUV区域中高反射率光学元件结合使用的总脉冲能达到了〜1μJ，允许观察40 eV中央XUV光子能量引起的双电荷NE状态。理论上还通过二阶时间依赖性扰动理论方程来研究强烈的脉冲序列与NE的相互作用。这项工作的结果以及进行Xuv-Pump-Xuv探针实验的可行性构成了许多潜在应用的强大工具。这些包括脉冲计量学以及对直接和顺序双电离及其电子相关效应的动力学的时间解决研究。
Two XUV-photon double ionization of Ne, induced by an intense few-pulse attosecond train with a ~ 4 fs envelope duration is investigated experimentally and theoretically. The experiment is performed at ELI-ALPS utilizing the recently constructed 10 Hz gas phase high-order harmonic generation SYLOS GHHG-COMPACT beamline. A total pulse energy up to ~1 μJ generated in Argon in conjunction with high reflectivity optics in the XUV region, allowed the observation of the doubly charged state of Ne induced by 40 eV central XUV photon energies. The interaction of the intense attosecond pulse train with Ne is also theoretically studied via a second-order time dependent perturbation theory equations-of-motion. The results of this work, combined with the feasibility of conducting XUV-pump-XUV-probe experiments, constitute a powerful tool for many potential applications. Those include attosecond pulse metrology as well as time resolved investigations of the dynamics underlying direct and sequential double ionization and their electron correlation effects.
