摘　　要：目的研究介质中任意非对称四态叠加多模泛函叠加态光场广义电场分量的高次和压缩特性.方法全量子多模高次压缩态理论分析.结果在一些特定的条件下,介质中多模泛函叠加态光场的广义电场分量可呈现出高次和压缩效应.结论介质中多模泛函叠加态光场的广义电场分量所呈现的高次和压缩现象的压缩幅度分别与压缩幂次数、各单模相干态光场的强度以及介质的增益或者吸收系数等非线性相关.Aim To study of the property of the higher-power sum-squeezing of the generalized electricalfield of multimode functional superposition state light field with the superposition of four unsymmetrical quantum statss in medium. Method By using the whole quantum multimode high-order squeezing state theory. Result Under certain conditions, the generalized electrical-field of multimode functional superposition state light field in medium shows the higher-power sum-squeezing. Conclusion The squeezing extent of the higher-order sum-squeezing shown in the generalized electrical-field of multimode functional superposition state light field in the medium is connected with squeezing power number, the intensity of the coherent state light field of the single mode, and the coefficient of the gain dielectric or the absorption dielectric.
