【Abstract】 We have studied the non\|resonance interaction between a V\|type three\|level atom and two\|mode cavity with Kerr medium. The results show that if the detunings of the two\|mode cavities are equal (\%δ\% 1=\%δ\% 2), when initial strength \%ξ\% of the two cavities remains unchanged and photon difference \%q\% of the two mode cavities is decreased, the non\|classical coherence degree between the two mode cavities is increased; when \%q\% remains unchanged and ξ is increased, the non\|classical coherence degree between the two mode cavities is decreased. When Δ δ =| δ \-2- δ \-1|=0 and \%q\% and \%ξ\% remain unchanged, the non\|classical coherence degree is decreased with the increase of Kerr effect, and the value of Δ δ has an importance influence on the non\|classical coherence degree. The results also show that when δ \-1= δ \-2, the second\|order coherence degree of the cavity 1 shows g \+\{2\}\-\{11\}<1, but the second\|order coherence degree of cavity 2 shows g \+\{2\}\-\{22\}<1 or g\+\{2\}\-\{22\}>1. On the other hand, the amplitude evolution of the second\|order coherence degree of two\|mode cavity is decreased due to the influence of Kerr effect.更多还原
