本文通过求解三维含时薛定谔方程,从理论上研究了共振条件下氢原子的光电子能谱与角分布随着激光脉冲载波包络相位(CEP)的变化规律.研究结果表明:在共振位置附近,光电子能谱的强度与CEP有强烈的依赖关系;进一步对各个分波的分析,可以确定共振电离初态的角量子数.此外,利用光电子的角分布信息,可以对多周期激光脉冲的初始相位信息进行高精度探测.
In this paper, by solving the three-dimensional time-dependent Schrödinger equation, the change rule of the photoelectron spectrum and angular distribution of hydrogen atoms under the resonance condition with the laser pulse carrier envelope phase (CEP) is studied theoretically.The results show that near the resonance position, The intensity of photoelectron spectroscopy has a strong dependence on CEP; further analysis of each partial wave can determine the angular quantum number of initial state of resonant ionization.In addition, using the angular distribution information of photoelectrons, the initial phase of multi-period laser pulse Information for high-precision detection.
