论文摘要
我们从理论上研究了使用三维经典模型受到强烈极化激光脉冲的原子的沮丧的双电离（FDI）。我们发现FDI概率的一种新颖的“膝盖”结构是强度的函数，这与非序列双电离概率的强度依赖性相似。当使用具有低电离势和短驱动激光波长的目标时，外国直接投资的观察更加有利。这归因于其中的回忆的关键作用，可以从FDI产生的光电子动量分布中推断出来。这项工作为通过圆极化的FDI动力学提供了新的物理见解。
We theoretically study frustrated double ionization (FDI) of atoms subjected to intense circularly polarized laser pulses using a three-dimensional classical model. We find a novel "knee" structure of FDI probability as a function of intensity, which is similar to the intensity dependence of nonsequential double ionization probability. The observation of FDI is more favourable when using targets with low ionization potentials and short driving laser wavelengths. This is attributed to the crucial role of recollision therein, which can be experimentally inferred from the photoelectron momentum distribution generated by FDI. This work provides novel physical insights into FDI dynamics with circular polarization.
