It has been shown that whether resonant or non - resonant interaction system, the kerr effect weakens the coupling of the field - atom, shortens the cycle of quantum collapses and revivals of the atomic level occupation and makes the nonclassical correlation properties steady. kerr effects on the properties of the correlation, on the correlation intensity between 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 it is changed the initial intensity of the light field. that is to say, kerr effect on the two interaction systems is accorded
