摘　　要：通过数值求解一维含时薛定谔方程 ,研究了原子在双色场作用下的电离和高次谐波及它们的相互关系。通过讨论两种不同的电离机制 :隧穿电离机制和过势垒电离机制 ,发现电离变化的规律很相似 ,但高次谐波谱的变化规律却很不同。By numerically integrating the one dimensional time dependent SchrAo¨Gdinger equation, the ionization and high harmonic generation of a model atom submitted to two color laser fields are investigated. By considering two different ionization mechanisms: the tunneling ionization regime and the over the barrier ionization regime, it is found that the ionization behaviors are quite similar, while the high harmonic generation behaviors are very different. The results demonstrate the possibility of phase control of atomic processes by using two color fields.
