摘　　要：构造了由多模相干态|{Zj}〉q、多模真空态|{0j}〉q和多模相干态的相反态|{-Zj}〉q线性叠加组成的第Ⅰ类三态叠加多模叠加态光场|ψ(3)1〉q,利用多模压缩态理论,研究了态|ψ(3)1〉q中广义电场分量的等幂次高次和压缩特性.结果表明,在一定条件下,态|ψ(3)1〉q的广义电场分量(即第二正交相位分量)可分别呈现出周期性变化的等幂次奇数模与偶数次、偶数模与奇数次、偶数模与偶数次、奇数模与奇数次的高次和压缩效应.The first kind of the three state superposition multimode superposition state light field ψ(3)1>q is constructed that is composed of multimode coherent state light field {Zj}>q, multimode vacuum state light field {0j}>q and contrary state {-Zj}>q of multimode coherent state light field {Zj}>q and that is based on the linear superposition principle of quantum state in quantum mechanics. Then the multimode squeezed state theory is utilized to study the effects of equalpower higherpower sum squeezing of generalized electric field component in the state ψ(3)1>q . It is found that under certain and fixed conditions, the generalized electric field component (or the second perpendicular phase component) of the state ψ(3)1>q can always display generalized nonlinear equalpower oddnumbermode with evennumberpower, evennumbermode with oddnumberpower, evennumbermode with evennumberpower, or oddnumbermode with oddnumberpower higherpower sum squeezing effects respectively and periodically.
