强场与级联三能级原子相互作用中的光子聚束与反聚束效应

Bunching and Antibunching Effects of Photon in the Interaction of a Cascade Three-level Atom with Strong Coherent Field of Initial State

本文采用数值计算方法研究了强相干初态光场与级联型三能级原子相互作用中的光子聚束与反聚束效应.结果表明:辐射光子主要表现为反聚束性质,且随着n值的不断增大,场与原子的非线性耦合越来越强,重复地出现复苏收缩现象。

In this paper,the bunching and antibunching effects of the photon in the interaction of a cascade three-level atom with strong coherent field of initial state are studied by numerical calculation . The results show that, the antibnnching effect of the radiative photons is displayed mainly; with the increasing of the value of n, the nonlinear coupling between the field and atom is getting stronger and stronger, and the phenomenon of the revival shrink appear repeatedly.
