【Abstract】 The state function for the interaction of a Λ type three level atom with two mode SU(1,1) coherent states in a Kerr like medium is derived.By using the state function it is studied that the influence of the Kerr effect on the Λ type three level atomic occupation probabilities,the two mode intensity correlation function,the Cauchy Schwartz inequality,and the second order correlation function for each mode.The results indicate that the Kerr effect weakens the coupling of the field atom and shortens the period of quantum collapses and revivals of the atomic level occupation.Kerr effects on the properties of the correlation,on the correlation intensity bewteen the two mode,on the photon number distribution and on the bunching or antibunching effect of the two mode SU(1,1) coherent states produce obviously different characters when the initial intensity of the light field is changed.更多还原
