【摘要】 对于在ω 2ω双色场作用下的原子 ,在两种不同电离机制下探讨了电离过程的相位效应。结果发现在隧穿机制下总电离率随相对相位的变化呈“∩”形 ,而在过势垒机制下呈“∪”形。研究说明利用双色场对原子电离过程进行相位控制是可行的更多还原

【Abstract】 For an atom under the action of ω 2ω two color fields, the phase effects of ionization process in different ionization regimes are investigated. The dependence of ionization possibility on relative phase is found in tunneling regime being a shape of "∩", while in the over the barrier regime being a shape of "∪". Our results demonstrate the possibility of phase control of ionization process by using two color fields.更多还原
