摘　　要：利用多模压缩态的一般理论,研究了由多模泛函相干态光场和多模泛函虚相干态光场组成的一种两态叠加多模泛函叠加光场的高次和压缩特性,结果发现,当腔模总数和压缩次数之积为偶数时,在光场的某些特定等相位面上,态总可呈现等幂次和压缩效应,各模经典强度的空间分布函数对态的高次和压缩效应的压缩程度和压缩深度产生直接的影响,随着光场经典强度空间分布函数的变化,态中不同模所呈现的高次和压缩效应的压缩程度和压缩深度在空间的分布是各向异性的.Utilized the general theory of multimode squeezed state, the squeezing properties of a new kind of multimode superposition state which composed by multimode functional coherent state and multimode functional imaginary coherent state is studied, and it is found that, when the products of sum-number of cavity-modes and squeezing number is an even number, the state can present equal-power sum squeezing effect in some special equal-phase-surface; The spatial distribution of classical intensity of the light-field has a direct influence upon the squeezed degree and the squeezed depth of generalized nonlinear equal-power sum-squeezing of the state ,and with the change of the spatial distribution of classical intensity of each mode, the squeezed degree and the squeezed depth of each mode of the state are anisotropic in spatial distribution.
