摘　　要：本文利用非相对论量子电动力学理论，研究了高 Ｑ Ｋｅｒｒ介质腔中，二能级原子与单 模辐射场多光子相互作用过程中光场相位的演化规律，着重讨论了强场条件下，类 Ｋｅｒｒ介质与单 模辐射场的耦合强度 Ｘ、失谐量△和多光子跃迁数 ｋ对光场的相位概率分布、相位涨落及频率漂 移的影响．The properties of the phase evolution in the system of a single-mode field interacting with a two-level atom via multiphoton process in a high Q cavity filled with the Kerr-like medium are studied by means of the non-relativistic quantum electrodynamics. The influences of coupling constant X, frequency detuning △ and transfering number k on the phase probability distribution, the phase diffusion and the frequency shift are emphatically discussed under the strong field condition.
