摘要
文章在文献 2的基础上 ,利用多模不等幂次压缩理论[7] 研究了第Ⅱ类[2 ] 两多模相干态的叠加态光场｜Ψ( 2 )2 〉q 的不等高次Y压缩效应。结果发现 :1.当各模压缩幂次数Nj 为偶数时 ,态 ｜Ψ( 2 )2 〉q 恒处于不等幂次Nj—Y 最小测不准态。 2 .当各模压缩幂次数 Nj为奇数时 ,｜Ψ( 2 )2 〉q 的第一或第二正交分量在一定条件下呈现出不等幂次Nj 次方Y压缩效应。文献 2的研究结果 ,仅仅只是该文章的普遍性结果在Nj =N (j =1,2 ,3,… ,q)这一条件下的特例。
On the basis of reference 2, the paper probes the squeezing effects of unequal-order higher-power Y-squeezing in the second kind of multimode superposition state light field with the superposition of two quantum state by using the definition of multimode squeezing. It is found that when the the squeezing orders of each mode is even number, the state |Ψ (2) 2> q is always in N j-Y minimum uncertainty state; when the squeezing orders of each mode is odd number, under some conditions the state |Ψ (2) 2> q can also present N j-th power Y-squeezing that changes periodically; the result of reference 2 is only a particular example under the certain condition N j=N of this paper's universal results.
