摘　　要：利用全量子理论,研究了Kerr介质中单模光场与V型三能级原子依赖强度耦合的相互作用系统中光场的压缩效应.采用数值计算的方法讨论了Kerr介质与辐射场的耦合系数χ和初始场平均光子数对光场压缩的影响.结果表明:Kerr效应对光场的压缩起着不同程度的减弱作用,适当大小的初始场平均光子数有利于光场的压缩.The time evolution of Light squeezing in the system of single-mode field interacting with V-type three-level atom via intensity-dependent coupling in Kerr medium is studied by means of the quantum theory. The effects of the coupling constant χ and the initial average photon numbers on the squeezing are discussed by the method of the numerical calculations. The result shows that Kerr effect has decreased the atomic dipole squeezing in various degrees the Proper initial average photon numbers be propitious to the squeezing of light.
