摘　　要：对Ｖ型三能级原子系统与双激光场相互作用时诱发的量子干涉效应进行了研究，通过在原子能级几率振幅随时间演化的耦合方程中引入一个上两能级交叉耦合干涉项，讨论和分析了在不同条件下交叉耦合干涉项的相消作用以及量子干涉效应对原子基态几率和原子系统受激吸收特性的影响．Quantum coherence induced by two lasers has been studied in V-shaped threelevel system. A coherence cross term is introduced into three coupled equations of the atom system. Under different conditions, we discuss the destructive interference of cross coupling and investigate the influence of quantum coherence effect on probability for ground state occupancy and characteristic of stimulated absorption.
