研究了二项式光场与V 型量子拍频三能级原子作用系统中光场的压缩特性及系统参数对光场压缩的影响 .数值计算表明 :当光场与三能级原子作用失谐量增大时 ,光场涨落呈现出周期性 ,平均值下移 ,压缩时间延长 ;选择合适的系统参数可使光场完全被压缩 ,产生完全压缩光 .
The field squeezing effect of the binomial state for the optical field interacting with V-type quantum-beat three-level atom is studied. The Squeezing properties are strongly related to the detuning parameters of the system. The results obtained by numerical method show that, with the increasing detuning between the three-level atom and the optical field, the fluctuation of the field occurs periodically, the average value decreases and the squeezing time of the optical field is prolonged. Moreover, the radiation field can stay squeezed via choosing optimal parameters of the system.
