根据量子力学中的态叠加原理,构造了由多模复共轭相干态|{z(a)*j}〉q和多模复共轭相干态|{z(b)*j}〉q的相反态|{-z(b)*j}〉q的线性叠加所组成的非对称两态叠加多模量子叠加态光场|ψ(2)1f〉q,利用多模压缩态理论研究了态|ψ(2)1f〉q的等幂高次和压缩特性,结果表明:1)当R(a)j=R(b)j和ψ(a)j-ψ(b)j=士(2k+1)π(k=0,1,2,3……),态|ψ(2)1f〉q的两个正交相位分量均处于N-H最小测不准态的结果;2)当R(a)j=R(b)j=Rj和ψ(a)j=ψ(b)j=ψj,态|ψ(2)1f〉q的等幂高次和压缩与文献3的结果相似;3)当R(a)j≠R(b)j=Rj和ψ(a)j=ψ(b)j=ψj,且q∑j=1ψj和θ(R)pq-θ(R)nq=△θ满足一定条件时,无论qN为奇数还是偶数,态|ψ(2)1f〉q的两个正交相位分量均可分别呈现周期性变化的等幂高次和压缩效应,但qN为奇数时的压缩深度大于qN为偶数时的压缩深度.
