摘　　要：根据量子力学中态的线性叠加原理 ,构造了由多模泛函相干态及其相反态、多模复共轭泛函相干态及其相反态这四个态等强度线性叠加组成的多模泛函叠加态光场 |Ψ( 4) (fj) >q。利用多模压缩态理论 ,研究了态 |Ψ( 4) (fj) >q 的不等幂次和压缩特性 ,结果发现 ,当各模的压缩次数之和、各模经典初始相位和经典强度的空间分布函数等满足一定的条件时 ,态 |Ψ( 4) (fj) >q 可呈现一定次数的不等幂次和压缩效应 ,其压缩程度。It is constructed in this paper that the four-states superposition multimode functional superposition state light-field |Ψ (4) *(f j)> q composed of four multimode functional coherent state through equal intensity.Utilized the unequal-power sum squeezing theory,the properties of unequal-power sum squeezing of the state |Ψ (4) *(f j)> q is studied,and it is found,when the add of squeezing number,the spatial distribution function of classical initial phase of each vertical order,the spatial distribution function of classical intensity of each mode and other parameters satisfied to different conditions,the state |Ψ (4) *(f j)> q can present certain power unequal-power sum squeezing,the squeezing degree and depth of each mode are intensively connected with the spatial distribution function of classical initial phase of each vertical order and the spatial distribution function of classical intensity of each mode of the state |Ψ (4) *(f j)> q.
