We use the improved quantitative rescattering (QRS) model to simulate the experimentally measured correlated two-electron momentum distributions (CMDs) for nonsequential double ionization (NSDI) of Ne exposed to intense elliptically polarized laser pulses with a central wavelength of 788 nm at a peak intensity of 5 ×1014 W cm⁻² for the ellipticities ranging from 0 to 0.25 (Kang et al 2018 Phys. Rev. A 97 063403). Only the CMDs for recollision direct ionization are calculated and the contribution from recollision excitation with subsequent ionization is ignored. With the assumption that recollisions occur after the zero crossing of the electric field along the major polarization, the QRS model successfully reproduces the experimentally observed asymmetry pattern of electron pairs in the CMDs for NSDI of Ne under elliptical polarization. By reducing the peak intensity claimed in experiment by about 30%, good agreement is achieved between the present results and the experimental measurements.

椭圆偏振激光场中氖非顺序双电离相关动量分布的模拟

我们使用改进的定量重散射（QRS）模型来模拟实验测量的相关双电子动量分布（CMD），用于暴露于峰值中心波长为 788 nm 的强椭圆偏振激光脉冲的 Ne 的非顺序双电离（NSDI）强度5 ×1014 对于椭圆度范围从 0 到 0.25 的W cm ^{−2 (Kang}等人2018年物理。牧师。A97063403）。仅计算重碰撞直接电离的 CMD，并忽略重碰撞激发和后续电离的贡献。假设沿主极化电场过零后发生重碰撞，QRS 模型成功地再现了椭圆极化下 Ne NSDI 的 CMD 中电子对的不对称模式。通过将实验中声称的峰强度降低约 30%，目前的结果与实验测量值之间取得了良好的一致性。
