本文利用双光子Ｊａｙｎｅｓ－Ｃｕｍｍｉｎｇｓ模型研究了理想腔体中二能级原子的双光子辐射谱，在不同的初始条件下给出了双光子辐射谱对频率的依赖关系。研究结果表明：双光子辐射谱不仅依赖于原子的初始状态和光场的统计性质，Ｓｔａｒｋ效应对双光子辐射谱也有很明显的影响，它使谱峰发生移动和使谱峰间距发生变化。
In this paper, the two-photon Jaynes-Cummings model is used to study the two-photon emission spectra of two-level atoms in an ideal cavity. The dependence of the two-photon emission spectrum on the frequency is given under different initial conditions. The results show that the two-photon radiation spectrum not only depends on the initial state of the atom and the statistical properties of the light field, but also has a significant effect on the two-photon radiation spectrum. Stark effect shifts the spectrum peak and changes the peak spacing.
