摘　　要：构造了由多模真空态、多模复共轭相干态、多模复共轭虚相干态及后两者的相反态的线性叠加所组成的一种五态叠加多模叠加态光场|Ψ(5)〉q.利用多模压缩态理论研究了态|Ψ(5)〉q中广义电场分量的等幂次N次方H压缩特性.结果发现:态|Ψ(5)〉q是一种典型的五态叠加多模非经典光场;在一定条件下,态|Ψ(5)〉q的广义电场分量可呈现出周期性变化的广义非线性等幂4m次方H压缩效应.It is constructed that multimode superposition state light field ｜ψ^（5）〉q which is composed of the linear superposition of five macroscopically distinguishable quantum states named multimode vacuum state, multimode complex conjugation imaginary coherent state, the contrary state of multimode complex conjugation imaginary coherent state, multimode complex conjugation coherent state, and the contrary state of multimode complex conjugation coherent state. By utilizing the theory of multimode squeezing states established recently, it is found that the state ｜ψ^（5）〉q is a type of five state superposition multimode nonclassical light field, and under certain and fixed conditions, the generalized electricfield component in the state ｜ψ^（5）〉q can display the effects of generalized nonlinear equal-power 4 m - th power H-squeezing which changes periodically.
