摘要
采用相互作用绘景,利用全量子化方法研究了压缩相干态光场与两个耦合二能级原子相互作用过程中,光子统计演化的规律;讨论了光场的压缩因子γ,相干振幅分量模平方|α|2、原子-场的耦合系数λ和原子间的耦合系数g对受激辐射场的平均光子数<n(t)>的影响,并揭示了它们之间的联系。
The photon statistical evolution in the process of two coupling two-level atoms interacting with the squeezed coherent state light field is investigated by means of the interacting picture and the quantum theory. Meanwhile, the influence of the squeezed light field factor γ, the coherent vibration amplitude |α|2 of the field-atom, the coupling constant g of two atoms and the coupling constant λ of atom-field on the mean photon number <n(t)> of stimulated field are also discussed. The relations of them are revealed.
