摘要
利用多模压缩态理论 ,研究了由多模复共轭相干态 | {Z j}〉q(j =1,2 ,3,… ,… ,q)、多模复共轭相干态的相反态 | { -Z j}〉q 和多模虚相干态 | {iZj}〉q 的线性叠加所组成的第Ⅴ类三态叠加多模叠加态光场 | ψ( 3)5〉q 中广义电场分量的等幂次N次方Y压缩特性 .结果发现 :当压缩次数N =2 p且 p =2m + 1(m =0 ,1,2 ,… ,… )时 ,在一定的条件下 ,态 | ψ( 3)5〉q 的广义电场分量 (即第二正交相位分量 )可呈现出周期性变化的、偶数次的等幂次 2 (2m + 1)次方Y压缩效应 .
It is constructed that the fifth kind of multimode superposition state light field |ψ (3) 5> q Which is composed of the linear suerpositions of macroscopically distinct three quantum states named multimode complex conjugation coherent state |{Z * j}> q , the contrary state |{-Z * j}> q of multimode complex conjugation coherent state |{Z * j}> q and multimode imaginary coherent state |{iZ j}> q. By utilizing the theory of multimode squeezed states, the generalized nonlinear even number power equal power N th power Y squeezing effects of generalized electric field component in the state |ψ (3) 5> q is studied firstly in detail. It is found that: if the squeezed power number N=2p and p=2m+1(here, m=0,1,2,...,...), Under some fixed conditions, the generalized electric field component in the state |ψ (3) 5> q can always display the effects of even number power generalized nonlinear equal power 2(2m+1) th power Y squeezing that changes periodically and alternatively.
