摘　　要：根据量子力学的线性叠加原理,构造了由多模相干态光场{zj(a)*}〉q和多模相干态光场态{zj(b)*}〉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H压缩。结果表明:当满足一定相位条件时,无论qN奇数还是偶数态ψ〉q的两个正交分量周期性地呈现任意阶等阶N方H压缩效应。Based on the liear superposition theory in the quantum mechanics,a kind of amplitude - mixing nonsymmetry superposition light field stateψ > q isconstituted by multi - mode coherent light field state{z j(a)* } > q and{z j(b)* } > q .By using higher - order squeezing theory in multi - mode state,equal - order Nth power H-squeezing propertiesof theψ > q isfound:when the certain phase conditionsare satis - fied,the two quardrature componentsofψ > q present any order equal - order Nth power H - squeezing which changesperiodically.
