光腔中光子数态的形成

The Formation of the Number State in the Optic Cavity

以单光子跃迁Ｊ－Ｃ模型为基础研究了大量激发态原子逐个穿越光腔后，腔内光场统计分布的变化特性，给出了纯光子数态的形成条件及光场的挤压效应的一般规律。腔场稳定时。

Base on the singlephoton transition JC model,The transformation characteristies of light field statistic distribution in cavity which is after a large number of excited atoms passing through the cavity in ones are studied.The forming conditions of the pure photon number states and the general rule of extruding effects of the light field are obtained.the fleeing atoms maintain their ineident excited states when the light field in the cavity is stable.
