摘要: 用Kulander等人发展的方法计算了双色光电离率随φ的变化,发现了当双色光场强度超过阈值时R-φ关系的转变,与经典方法计算的结果作了比较。

关键词: 双色光电离, 隧穿电离, 越垒电离, 阈值场强

Abstract: Ionization rate of Hydrogen atom in a two-color laser field is calculated by using the method developed by Kulander etc.Change of ionization rate-phase relation is found when the field intensity goes up to threshold and comparison with classical calculation has been done.

Key words: two-color ionization, tunneling ionization, over-barrier ionization, threshold field intensity
