摘　　要：根据量子力学的叠加原理 ,构造了由多模复共轭相干态光场 | {Z(a) j }〉q 和 | {Z(b )j }〉q 叠加而成的非对称两态叠加多模叠加态光场 |Ψ〉q。利用多模压缩态理论 ,研究了态 |Ψ〉q 的等阶N方Y压缩 ,结果表明 :当满足一定相位条件时 ,无论N为奇数还是偶数 ,态 |Ψ〉q 的两个正交相位分量周期性地呈现任意阶等阶N方Y压缩效应。Based on the Superpositon theory in the quantum mechanics,a kind of amplitude-mixing nonsymmetry superposition light field state｜Ψ〉_ q is constituted by complex conjugate multi-mode coherent states ｜｛Z ( a )* _ j ｝〉_ q and ｜｛Z (b)* _ j ｝〉_q.By using higer-order squeezing theory in multi-mode state,It is studied that equal-order Nth Power Y-Squeezing properties of the ｜Ψ〉_ q ,it is found:When the certain phase conditions are satisfied,The two quardrature phase components of ｜Ψ〉_ q present any order equal-order N th power Y-squeezing which changes periodically,whether N is odd number or even number.
