Stark效应对理想腔体中二能级原子双光子辐射谱的影响

Influence of Stark Shift upon the Two Photon Emission Spectrum in an ldeal Cavity

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。

The two--photon emission spectra in an ideal cavity has been studied under various initial conditions. The results show that the emission spectra depend on not only the initial state of the atom and properties of the field, but also the Stark shift of the atomic levels. The peaks of spectrum are shifted and the interval of peaks broadened by Stark shift.
