摘　　要：首次研究了具有普遍意义的非对称两态叠加多模叠加态光场的N次方X压缩特性 ,结果发现 :当各模初始相位、态间初始相位差、各模光子数以及压缩幂次分别满足各自的条件时 ,多模量子态光场呈现出周期性变化的广义非线性差压缩 (即N次方X压缩 )效应 ;进一步地分析表明 :第Ⅰ、Ⅱ类多模叠加态光场的N次方X压缩是本文所讨论的特例。The property of N-th power X-squeezing in a kind of intensity asymmetrical multi mode superposition state light field with the superposition of distinguishable two quantum state is firstly studied in detail by using of the general theory of generalized nonlinear difference squeezing in multi mode radiation field. It is found that the kind of multi mode superposition state light field mentioned above presents generalized nonlinear difference-squeezing effect (that is N-th power X-squeezing effect) that changes periodically if some conditions are satisfied respectively by the initial phase of each mode, or by the initial phase difference between the two components, or by photons of each mode, or by squeezing power. By further analysis demonstrate, it is demonstrated that the properties of N-th power X-squeezing in the first and second kind of multi mode superposition state light field are only particular examples of the discussion in this paper under certain conditions.
