摘　　要：利用多模压缩态理论 ,研究了多模虚共轭相干态 |{ i Z*j }〉q与多模真空态 |{ 0 j}〉q的叠加态 |{ Ψ(2 )p }〉q的广义非线性等阶 N次方 Y压缩特性 .结果发现态 |{ Ψ(2 )p }〉q是一种典型的多模非经典光场 ,它在一定的条件下 ,可呈现出周期性变化的、任意奇数阶和任意偶数阶的等阶 N次方 Y压缩效应 ,而在另外的条件下 ,则可呈现出等阶 N次方By using the theory of multi mode squeezed state,the property of generalized nonlinear equal order N th power Y squeezing of the state |{Ψ (2) p}> q which is made of the linear superposition of macroscopically distinct two quantum state named the multi mode imaginary conjugate coherent state |{iZ * j}> q and multi mode vaccum state |{0 j}> q is studied firstly in detail.It is found that the state mentioned above is a kind of typical multi mode nonclasical light field.Under the certain conditions,the state mentioned above presents any odd order and any even order equal order N th power Y squeezing effect that changes periodically;new phenomenon of equal order N th power Y similitude squeezing is displayed if the specical conditions are satisfied.
