论文摘要
理论上使用时间依赖性的单中心方法研究了fenchone多光电离机构的不同状态中的光电子圆二色性（PECD）。特别是，我们通过圆形极化的400和814 nm光学激光脉冲或1850 nm红外线脉冲研究了对单色多光子或强场电离的手性反应。此外，考虑了短相干圆极化的413-1240 nm跨度脉冲的宽带电离。最后，研究了在相互正交方向上线性极化的相锁400和800 nm脉冲的两种颜色电离。有关Fenchone的单色多光子电离的当前计算结果与可用的实验数据一致。为了通过宽带和双重脉冲对fenchone的电离，目前的理论研究预测了大量多光子pecd。
Photoelectron circular dichroism (PECD) in different regimes of multiphoton ionization of fenchone is studied theoretically using the time-dependent single center method. In particular, we investigate the chiral response to the one-color multiphoton or strong-field ionization by circularly polarized 400 and 814 nm optical laser pulses or 1850 nm infrared pulse. In addition, the broadband ionization by short coherent circularly polarized 413-1240 nm spanning pulse is considered. Finally, the two-color ionization by the phase-locked 400 and 800 nm pulses, which are linearly polarized in mutually-orthogonal directions, is investigated. The present computational results on the one-color multiphoton ionization of fenchone are in agreement with the available experimental data. For the ionization of fenchone by broadband and bichromatic pulses, the present theoretical study predicts substantial multiphoton PECDs.
