摘　　要：构造了由偶数模多模复共轭奇相干态与多模复共轭偶相干态线性叠加所组成的第Ⅱ种偶数模四态叠加多叠模加态光场 |Ψ( 4)oe ,Ⅱ〉2q.利用多模压缩态理论 ,研究了态 |Ψ( 4)oe ,Ⅱ〉2q的等幂次高次差压缩特性 .结果发现 :在一定条件下 ,态 |Ψ( 4)oe ,Ⅱ〉2 q的两个正交相位分量可同时呈现出广义非线性等幂次高次差压缩效应 .The properties of equal-power higher power difference squeezing in the second even number mode four state superposition multi-mode superposition state light field which made up by even number mode multi-mode complex conjugation odd and even coherent is studied. The results show the two quadrature phase components of the state | Ψ (4) oe,Ⅱ> 2q appear as equal-power higher power difference squeezing simultaneously under special conditions.
