The squeezing property of the light in the system of twomode field interacting with two coupling atoms in Kerr medium is studied by means of quantum theory. The influences of the Kerr Medium and twomode field coupling constant χ,the initial average photon numbers n0 and the atomic initial state are discussed.
The statistic properties of photons in the system of two-mode squeezing vacuum field interacting with two coupling atoms in Kerr medium are studied by means of quantum theory.The influences of coupling constant χ, initial squeezed parameter r and the atomic initial state are discussed. The results obtained by means of numerical method show that the photon bunching and anti-bunching appear alternately, and the correlation of the two modes of light is both positive and non-classical. The periodical collapse-revival phenomenon of the time evolution of the second-order coherence degree of the two-mode field appears due to the influence of the Kerr effect. The periods of the collapse-revival become short up to disappearance with increasing Kerr effect.
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.
