摘　　要：构造了由多模虚共轭相干态 |{ i Z*j }〉q与多模真空态 |{ 0 j}〉q两者的线性叠加所组成的两态叠加多模叠加态光场 |{ Ψ(2 )p }〉q.利用多模压缩态理论 ,首次对该态的等阶 N次方 H压缩特性进行了详细研究 .结果发现 :态 |{Ψ(2 )p }〉q是一种典型的多模非经典光场 ,它可呈现出周期性变化的、任意阶的等阶 N次方 H压缩效应 .In this paper,a new type of multi mode supeposition state light field|{Ψ (2) p}> q is constructed,which is made of the linear superposition of macroscopically distinct two quantum states named the multi mode imaginary conjugate coherent state |{iZ (a)* j}> q and multi mode vaccum state |{0 j}> q repactively.By using the theory of multi mode squeezed state,the property of generalized nonlinear equal order N th power H squeezing of the state |{Ψ (2) p}> q is studied firstly in detail.It is found that the state metioned above is a kind of typical multi mode nonclasical light field.Under the certain conditions,the state mentioned above presents any order equal order N th power H squeezing effect that changes periodically.
