摘　　要：首次研究了两类多模薛定谔猫态 ( MSCS)光场 :|Ψ ( 2 )+〉q和 |Ψ ( 2 )- 〉q的不等阶 Nj次方 Y压缩特性。结果揭示了两态之间具有压缩相似及简并的性质 ;在各模压缩阶数 Nj( j =1 ,2 ,3,… ,q)分别取4mj、4mj+ 1、4mj+ 2以及 4mj+ 3( mj=0 ,1 ,2 ,3,… )的情况下 ,随着各模初始相位的变化 ,加上其它某些量子化或连续性条件 ,两类 MSCS均可呈现出周期性变化的任意不等阶 Nj次方 Y压缩效应。说明态 |Ψ( 2 )+〉q与 |Ψ( 2 )- 〉q是两种典型的多模非经典光场。The properties of unequalled order N j th power Y squeezing in the two new kind multimode Schr o ¨dinger state(MSCS) light fields:|Ψ (2) +> q and|Ψ (2) -> q are studied firstly in detail.It's result reveals that the squeezing properties of similitude and degenrate between the two kind states mentioned above,With the initial phase φ j(j=1,2,3,...,q) changing,and else some quantization or continuity conditions,the two kinds MSCS present periodically any unequalled order N j th power Y squeezing effect in the case of squeezing order N j of each mode is equal to 4m j,4m j+1,4m j+2 and 4m j+3(m j=0,1,2,3,...) respectively.It is demonstrated that the state |Ψ (2) +> q and |Ψ (2) -> q are two kinds of typical multimode nonclassical light fields.
