摘要：

对二能级原子与单模辐射场相互作用系统的哈密顿量进行分析，找出光场与原子之间耦合系数与光场频率及谐振腔体积之间的关系。通过利用谐振腔的腔镜振动机制，研究了腔镜振动对光场模式及对腔体积的影响，最终找出辐射场与原子之间耦合系数与场频变化之间的关系。

关键词: 量子光学, 耦合系数, 变频率光场, 腔镜振动

Abstract:

The interaction Hamiltonian of a two-level atom and a single-mode radiation field with time-varying frequency is studied. The special attention is paid on the relationship between the atom-field coupling and the frequency of the cavity field or the volume of the cavity. By using the vibration mechanism of the cavity mirror, we studied the impact induced by the vibration of cavity mirror on the optical mode inside the cavity and on the volume of the cavity, and the exact relationship between the time-varying frequency of the cavity field and the atom-field coupling constant is found.

Key words: q quantum optics, atom-field coupling constant, time-varying-frequency field, vibration of cavity mirrors
