ω-2ω双色场相位控制电离:隧穿电离与过势垒电离的比较
ω-2ω Two-Color Phase Control of Ionization: Comparison of Tunneling and Over-the-Barrier Regimes
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.
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.
