The quantum properties of light in the system of Λ-type three-level atom interacting with radiation fields in binomial states are studied by means of quantum theory.The influences of the initial states of the Λ-type three-level atom and the parameter of the binomial optical fields on squeezing of the optical field and the second-order coherence degree are investigated in detail.As the detuning parameter of atom A and the parameter of the binomial optical fieldηare small,bunching and antibunching effect can be exhibited alternatively.With the increase of the parameters,the light field shows antibunching effect completely.If the detuning parameter of atomΔand the parameterηare chosen appropriately, the component X_1 of the light field in the coupling system will be squeezed during the certain time.The results indicate that the light field shows squeezing effects and continuous antibunching effect under a certain condition as it interactes with a A-type three-level atom.

By means of solving Schrdinger’s equation and numerical calculations, the radiation squeezing effects in the system of the binomial states field interacting with a moving Ξ-type three-level atom are discussed. The results indicate that the radiation field can show complete squeezing effects when the system parameters are selected appropriately.
