摘　　要：研究了V型三能级原子玻色-爱因斯坦凝聚体与双模压缩相干态光场相互作用系统中的光场压缩的特性.数值计算结果表明:光场的正交分量呈现周期性压缩,其周期与原子间相互作用密切相关,而最大压缩量与持续时间与初始光场的压缩因子有关.The squeezing properties of two-mode squeezed light interacting with V-type three-level atomic BEC is studied. The result shows that the fluctuation of quadrature components of light is squeezed periodically,the period of squeezing is closely correlated to the interaction between atoms in BEC, however the maximum of squeezing and duration time depends lightly on initial squeezing factor of light.
