| Abstract: | 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. |
