| 摘 要： | 应用全量子理论研究了在高Q Kerr介质腔中, 二能级原子与二项式光场相互作用系统中原子行为和光场的量子特性. 采用数值计算的方法, 详细讨论了光场参量和Kerr效应对原子布居反转和平均光子数的影响.研究发现当二项式光场处在中间态时, 在考虑Kerr效应的条件下,原子布居振荡加剧, 回复时间变短, 系统内平均光子数减少.

| Abstract: | The quantum properties of atom and light field in the system of a two-level atom interacting with binomial field inside a high-WTBXQ cavity filled with a Kerr medium are studied by means of quantum theory. By numerical method, the influences of field parameters and Kerr effect on the atomic population inverse and average photon number are discussed detailedly. The study shows when binomial field is in intermediate state between coherent state and Fock state, considering Kerr effect, oscillation of atomic population becomes intense, revival period becomes short and the average photon number of the system becomes less. |
