| 摘 要： | 本文利用量子电动力学理论和缀饰原于方法，对双光子Ｊａｍｅｓ－Ｃｕｍｍｉｎｇｓ模型中单模激光场的稳态亚泊松光子统计性质进行了系统研究。结果表明：激光上能级相对泵浦参量Ｘａ具有一个确定的阈值Ｘａｔ；当Ｘａ＞Ｘａｔ时，光场呈现亚泊松光子统计；而当Ｘａ＞＞Ｘａｔ时，光场将呈现出深度且完全恒定的亚泊松光子统计。

| Abstract: | In this paper the quantum-electrodynamics theory was used, firstly and systematically, to study Sub-Poissonian photon statistical characteristics of two-photon JaynesCummings model in a single-mode laser light field. The results show that there is a fixed threshold Xat for the relative pumping parameter Xa of the upper laser level; if Xa > Xat,the Sub-Poissonian photon statistics occurs; and if Xa >> Xat, the deep degree and constant Sub-Poissonian photon statistics appears. |
