摘要
利用半经典理论,以Λ型三能级原子系统为例,研究了电磁感应透明的物理机制.通过暗态、缀饰态和密度矩阵方程三种理论,解释了当激光场与原子系统相互作用时,原子在光场诱导的跃迁通道间发生量子相干效应是出现电磁感应透明的原因.
The physics mechanism of electromagnetically induced transparency in a A-type three-level atomic system was investiga-ted by means of the semiclassical theory. The electromagneticaUy induced transparency is an effect of quantum interference be-tween two laser-induced channels when the laser field interacts with an atom. The explanations of these phenomena are given by u- sing the dark state, the dressed states and the density-matrix equations.
