Theoretical studies on the momentum distribution of rescattering electron of atoms and molecules in intense laser field and its applications

在第一性原理模拟的基础上，（1）得到了强激光场中重散射电子的动量分布，并利用所得到的重散射电子的动量解释了He原子非顺序双电离的物理起源;（2）揭示了激光辅助原子和分子光电离的机理，提出了一种利用阿秒时域强激光控制材料透明性的方法，并在实验中得到了应用。

Based on our first principle simulation, (1) we have obtained the rescattering electron momentum distribution in the intense laser field, and illustrated the physical origination of the non-sequential double ionization of He using the obtained rescattering electron momentum ; (2) we have discovered the mechanism of the laser assisted photoionization of atoms and molecules, and proposed a way to control the transparent of materials by the intense laser in atto-second time domain and the proposal method has been used in experiments.
