摘　　要：构造了由多模虚相干态 | {i Zj}〉q、多模虚相干态的相反态 | {- i Zj}〉q和多模真空态| {0 j}〉q这三种不同的量子光场态的线性叠加所组成的第 类三态叠加多模叠加态光场| ψ( 3)2 〉q.利用多模压缩态理论 ,研究了态 | ψ( 3)2 〉q的广义非线性等幂次 2 m+ 1次方 Y压缩特性 .结果发现 :在压缩次数 N =2 m+ 1 ( m=0 ,1 ,2 ,3,… ,… )的条件下 ,只要各模的初始相位和态间的初始相位差分别满足一定的取值条件 ,态 |ψ( 3)2 〉q就可呈现出周期性变化的、任意奇数次的广义非线性等幂次 N次方The second kind of the three state superposition multimode superposition state light field|ψ (3) 2> q is constructed,that is composed of multimode imaginary coherent state|{iZ j}> q,contrary state|{-iZ j}> q of multimode imaginary coherent state |{iZ j> q and multimode vaccum state|{0 j}> q.And then the multimode squeezed state theory suggested by YangZhiyong and Hou Xun is utilized to study the properties of generalized nonlinear equal power (2m +1) th power Y squeezing of the state|ψ (3) 2> q mentioned above.It is found that under the condition of the squeezing power number N=2m+1(here,m=0,1,2,3,...,...),the first and the second perpendicular phase components of the state |{ψ (3) 2> q can all display any odd number power generalized nonlinear equal power N th power Y squeezing respectively,which changes periodically while some certain and fixed conditions are satisfied by the initial phase of each mode in the state|ψ (3) 2> q,and while the initial phase difference between any two components of the state|ψ (3) 2> q change continuously within their own fixed and closed regions respectively.
