摘　　要：根据量子力学中态的线性叠加原理,构造了由多模真空态、多模相干态、多模相干态的相反态和多模虚相干态的线性叠加所组成的真空场注入四态叠加多模纠缠态(即4SMES)光场.利用多模压缩态理论研究了上述光场中广义电场分量的等幂次高次和压缩特性.结果发现:真空场注入4SMES光场是一种典型的四态叠加多模非经典光场;在一定条件下,该光场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+2次和压缩效应.According to the linear superposition principle of state in quantum mechanics, the four-state superposition multimode entangled state （4SMES） light field is constructed, that is composed of multimode vacuum state, multimode coherent state and its contrary state, multimode imaginary coherent state. Then the multimode squeezed state theory is utilized to study the characteristics of generalized nonlinear equal-power higher-power sum squeezing of the generalized electric-field component in the vacuum state immiting 4SMES light field mentioned above in detail. It is found that the vacuum state immiting 4SMES light field is a type of four-state superposition multimode nonclassical light field,and under certain fixed conditions,the generalized electric-field component in the 4SMES light field can display generalized nonlinear equal-power 4m＋2-th power sum squeezing effects which change periodically.
