摘　　要：构造了由多模共轭相干态、多模复共轭虚相干态及多模真空态3态线性叠加所组成的第 类3态叠加多模叠加态光场。利用多模压缩态理论,研究了此量子态的广义非线性不等幂次Nj次方Y压缩(即振幅压缩)效应。结果发现,只有当各单模的压缩次数Nj(j=1,2,…,q)为偶数时,此量子态在一定的条件下总可呈现出周期性变化的任意偶数次广义非线性不等幂次Nj次方Y压缩效应。The third of the three state superpositions multimode superposition state light field |ψ(3)3>q was constructed by linear superposition of multimode complex conjugation coherent state,|{Zj}>q multimode complex conjugation imaginary coherent state |{iZj}>q and multimode vaecum state |{0j}>q.By utilizing the theory of multimode squeezed states,the properties of generalized nonlinear unequalpower Njth power Ysqueezing (or amplitude squeezing) in the state |ψ(3)3>q was discussed.It is found that when the squeezing power of each mode Nj is even number only,and some certain conditions are satisfied,the first or second perpendicular phase component in the state |ψ(3)3>q can always display any even number power generialized nonlinear unequalpower Njth power Ysqueezing effeets respectively,which is comlementary,also changes periodically.
