| 摘 要： | 研究了二项式光场与二能级原子玻色--爱因斯坦凝聚（BEC）相互作用系统产生的原子激光的量子相关性质、压缩效应和振幅平方压缩效应。应用全量子理论，通过求解系统的海森堡方程,重点讨论了光场相关参数和原子相关参数对压缩深度、压缩频率的影响。结果表明，单模原子激光二阶相干度不随时间变化，原子激光具有周期性的压缩效应和振幅平方压缩效应，最大压缩深度由二项式光场相关参数决定，压缩频率依赖于原子与光场耦合系数，简要讨论了压缩效应和振幅平方压缩效应之间的区别和联系。

| Abstract: | The quantum correlation properties and squeezing properties of atomic laser are studied in the system of the binomial states field interacting with Bcse-Einstein condensate of two-level atoms,and the amplitude-squared squeezing effects of atomic laser are also discussed.The influence of field parameter and atom parameter on the depth and duration of squeezing are mainly investigated by solving the Heisenberg equation based on the entire quantum theory.The results show that the quantum correlation properties... |
