摘要

利用经典系综模型研究了椭圆偏振激光脉冲驱动的氩原子非次序双电离对激光强度的依赖. 计算结果显示, 沿激光偏振平面长轴方向, 电子对的关联行为依赖于激光强度, 在较高的激光强度下, 关联电子对的动量谱呈正关联, 并且在一、三象限呈现明显的V-型结构. 在较低的激光强度下, 关联电子对的动量谱呈强烈的反关联行为. 在激光偏振平面短轴方向, 关联电子对的动量谱在不同的激光强度下均呈现强烈的反关联行为. 通过分析非次序双电离的经典运动轨迹,证明末态电子之间的排斥作用对关联电子动量谱在激光偏振平面长轴方向的V-型结构, 以及短轴方向的反关联行为起决定性作用.

Abstract

With a classical ensemble model, we investigate the intensity dependence of nonsequential double ionization (NSDI) of argon atoms by elliptically polarized laser pulses. The results show that the correlated behavior of two electrons along the long axis of the laser polarization plane depends on the laser intensity. At the relatively high intensity, the correlated electron momentum spectrum displays a correlated behavior and shows V-like structures in the first and third quadrants. At the relatively low intensity, the correlated electron momentum spectrum shows a strongly anticorrelated behavior. For the different laser intensities, the momentum spectra of two electrons along the short axis of the laser polarization plane all show strongly anticorrelated behaviors. The analysis of the classical trajectories of NSDI shows that the final-state electron repulsion plays a decisive role in both the V-like shape along the long axis of the laser polarization plane and the anticorrelated behavior along the short axis of the laser polarization plane.
