摘　　要：构造了由多模复共轭相干态的相反态 |{ -Z(a) *j }〉q和多模虚共轭相干态的相反态|{ -Z(b) *j }〉q的线性叠加所组成的第 种强度不等的非对称两态叠加多模叠加态光场|Ψ(ab) 〉q.利用多模压缩态理论 ,研究了态 |Ψ(ab) 〉q 的等阶 N次方 H压缩特性 .结果发现 ,在腔模总数与压缩阶数这两者之积取奇数 ,则当各对应模的初始相位、各对应模的初始相位差 ,态间的初始相位差、以及光子干涉项的幅度之和等分别满足一定的量子化条件时 ,态 |Ψ(ab) 〉q的第一及第二正交分量可分别呈现出周期性变化的等阶 N次方 H压缩效应 .It is constructed the kind Ⅱ of different intensity of asymmetry state superimposition state light field |Ψ (ab) Ⅱ> q with two different kind of multi mode complex conjugation coherent state of contrary states |{-Z (a) * j}> q and multi mode imaginary conjugation coherent state of contrary state |{-iZ (a) * j}> q which is made of linear superimposition in this paper.By utilizing the theory of multi mode squeezed states,the property of equal order N th power H squeezing effect on state|Ψ (ab) Ⅱ> q .It is found that when qN=2p+1,no matter what p=2m or p=2m+1(m=0,1,2,3,...,...),if R (a) j ≠R (b) j and φ (a) j≠φ (b) j(j=1,2,3,...,q),and qj=1R (a)(2p+1) j≠qj=1R (b)(2p+1) j,while the quantization conditions are satisfied of initial phases of whole mode,the difference of initial phases of corresponding mode,the difference of initial phases of states and phone interference of range etc,the first and the second quadrature component of state|Ψ (ab) Ⅱ> q can always present the effect of periodic changed equal order N th power H squeezing.The result and the report at present is distinct.
