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S z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F x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。
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.
