研究了含级联双光子过程的多束缚态激光场诱导原子连续态结构系统中原子的相干捕获，给出了产生相干捕获的条件及暗态的表达式，讨论了原子初态和激光强度对原子相干捕获及粒子布居值在束缚态上分布的影响，揭示了原子相干对稳定里德伯原子的重要作用。

The atomic coherent population trapping is studied in a multilevel laser-induced continuum structure system including cascade two-photon processes. The condition leading to the atomic coherent population and the dark state are given explicity. The effects of atomic initial state and the laser intensity on the amount of population trapped in the dark state and the populations distributed in the atomic bound states are discussed. Influence of...
