超短强脉冲Laser分子双电离中关联电子的复杂动力学
Complex Dynamics of Correlated Electrons in Molecular Double Ionization by an Ultrashort Intense Laser Pulse
摘要：
利用半经典准静态模型，研究了在双中心库仑势和强激光场共同作用下，两个关联电子的复杂动力学行为。该模型计算能够再现氮分子的实验数据为宽范围的激光强度从隧穿到过势垒制度，并预测一个显着的对齐效果的双离子产量的比率。经典的轨道分析可以揭示亚循环分子双电离动力学。
英文摘要：
With a semiclassical quasi-static model we achieve an insight into the complex dynamics of two correlated electrons under the combined influence of a two-center Coulomb potential and an intense laser field. The model calculation is able to reproduce experimental data of nitrogen molecules for a wide range of laser intensities from tunnelling to over-the-barrier regime, and predicts a significant alignment effect on the ratio of double over single ion yield. The classical trajectory analysis allows to unveil sub-cycle molecular double ionization dynamics.
