摘　　要：构造了由多模虚共轭相干态的相反态 ｜ { -iz j} >q 与多模真空态 ｜ {Oj} >q 这两者的线性叠加所组成的一种新型的两态叠加多模叠加态光场 ｜Ψ(2 )n >q。利用多模压缩态理论 ,详细研究了态 ｜Ψ(2 )n >q的等阶N次方Y压缩特性 ,并由此揭示出一系列具有重要意义的新的压缩现象。A new type of multi-mode superposition state light field |Ψ (2) n> qis constructed, which is made of the linear superposition of macroscopically distinct two quantum state named the contrary state |{-iz * j}> q of multi-mode imaginary conjugate coherent state |{iz * j}> q and multi-mode vacuum state |Ψ (2) n> q in this paper. 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) n> q mentioned above is studied firstly in detail. A series of significative new squeezing phenomenons are displayed.
