摘　　要：研究了在充满Kerr介质的高Q腔内三能级原子与双模光场相互作用系统中光场的压缩效应 ,分析了腔中Kerr介质对初态分别为双模压缩真空态和SU(1,1)相干态的两种光场的双模压缩以及双模和压缩的影响 ,指出了Kerr效应对初态为SU(1,1)The field squeezing in the system of a three level atom embedded in a high Q cavity filled with Kerr medium is investigated.The effects of Kerr medium on two mode field initially in two mode squeezed vacuum state and SU(1,1) coherent state are analyzed.It is found that the influence of squeezing for the field initially in SU(1,1) coherent state is more evident that for the field initially in two mode squeezed vacuum.
