摘要
根据量子力中的线性叠加原理,构造了由多模奇相干态和多模复共轭虚奇相干态这两者的线性叠加所组成一种典型的四态叠加多模叠加态光场 ,通过对态 的等幂次振幅压缩特性的研究发现:1)当压缩次数N=4P(P=1,2,3,…)时,若各模初始相位(?)j、态间相位差θ1-θ2等相关参数满足一定的不同条件时,态 的第一正交分量总可呈现不同程度的、周期性变化的等幂次振幅压缩效应;2)当压缩阶数N=4P'-2(P'=1,2,3,…)时,若各模初始相位(?)j、态间相位差θ1-θ2等相关参数满足一定的不同条件时,态 的第二正交分量总可呈现不同程度的、周期性的等幂次振幅压缩效应.
According to the linear superposition principle in quantum mechanics,the superposition light field composed by multimode odd coherent state and multimode complex
conjugation imaginary odd coherent state Utilized the multimode squeezed state theory.the
properties of equal-power N-th power Y-squeezing of the state is studide,and it is found that:1)when squeezing number N=4P (P=1,2,3,...),if the initial phase of each vertical order (?),the phase difference θ1-θ2 and other parameters take different fixed value,the first quadrature component
of the state always presents different degree and periodic changing equal-order N-th power Y-squeezing;2)when squeezing number N=4P'-2 (P'=1,2,3,...) if the initial phase of each vertical order (?)j,the phase defference θ1-θ2 and other parameters take different fixed value,the second
quadrature component of the state always presents different degree and perindic changing equal-power N-th power Y-squeezing.
