中文摘要：

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.

英文摘要：

By solving the three-dimensional time-dependent Schrdinger equation, we have theoretically investigated the variation of photo-electron spectroscopy and angular distribution of hydrogen atom with carrier envelope phase （CEP） under the resonant condition. The results show that the intensity of photoelectron spectroscopy is strongly dependent on CEP near the resonant position; and the angular momentum quantum number of resonant initial-ionized state can be determined by further analyzing each partial wave. In addition, we can detect the information of initial phase of multi-cycle pulses with high accuracy by utilizing the information of angular distribution of photoelectron.
