摘　　要：采用时间演化算符方法,研究Λ-型三能级原子与双模腔场共振相互作用的辐射谱,尤其在真空场中拉比(Rabi)分裂.给出了辐射谱一般公式.并讨论在粒子数纯态光场激励下的辐射频谱结构.结果表明:一般辐射谱呈对称的12蜂结构.By means of time-evolution operator, we have studied the emission spectrum, especially the vacuum Rabi splitting of a ∧-type three-level atom interacted resonantly with two-mode cavity fields in the paper. The physical spectrum expression of radiation emitted by the atom is given. We have discussed the structure of the emission spectrum for inputs in pure number states. The results indicate that the structure of the resonant emission spectra of the atomic system has twelve peaks generally.
