摘　　要：通过光与物质相互作用的主方程计算了强场激励的二能级原子与单模腔耦合的稳态荧光谱.在腔场的强耦合作用下,三峰Mollow谱的每个成分都分裂为多重的,这种现象由腔场使原子修饰态能级漂移而导致的,荧光谱的具体结构则依赖于驱动场的拉比频率和原子-腔的耦合系数.We calculate the spectrum of resonance fluorescence from a two-level atom coupled to a single cavity mode and driven by a strong field from master equation. In the strong-coupling limit,each Mollow triplet component is split into a multiplet which can be explained by the shift of the dressed state of atom caused by the strong cavity field. The structure of the resonance fluorescence spectrum depends on the coupling coefficient of atom-cavity and Rabi frequency of driven field.
