| 摘 要： | 在旋波近似下，考虑光场频率随时间作正弦函数变化，研究了二能级原子与变频相干态光场相互作用系统中原子算符Sz 的压缩效应，利用全量子理论数值计算方法推导了压缩分量Fx 随时间变化的曲线，结果表明：光场频率变化对原子算符的压缩存在影响。

| Abstract: | In the rotating-wave approximation, the atomic operator squeezing effect in the system that consists of a two -level atom interacting with time -varying-frequency field is studied .Considering the field frequency varying with the time in the form of sine-function at the same time, by means of the quantum theory and numerical calculation,the curve varying with time is de-rived.The results show that atomic squeezing is affected by time -varying-frequency light-field. |
