摘　　要：构造了五态叠加多模泛函量子叠加态光场|ψ^(5)(fj)q。利用多模压缩态理论,研究了态|ψ^(5)(fj)q的广义电场分量在其不等强度非对称叠加条件广义非线性不等幂次Nj次方振幅压缩特性。结果发现:①对于态|ψ^(5)(fj)q的不等强度非对称叠加情形,在一定条件下,态|ψ^(5)(fj)q的广义电场分量就可呈现出任意次不等幂次且周期性变化的广义非线性Nj次方振幅压缩效应;②态|ψ^(5)(fj)q的多模泛函相干态中各模经典振幅和经典相位等的空间任意分布特征以及经典强度和经典振幅的任意非对称空间分布特征将对其不等幂次振幅压缩效应的压缩结果及压缩程度等产生直接的影响;③态|ψ^(5)(fj)q的广义非线性不等幂次振幅压缩效应的研究结果和结论具有普遍的理论意义。The five states superposition multimode quantum functional superposition light field state |ψ^(5)(fj)q is formed and the properties of the GN unequal-power higher-power Nj-power Y-S effects was further studied generally.The results indicated that ① when the state |ψ^(5)(fj)q is an unequal intensity asymmetrical superposition,while some certain conditions are satisfied the generalized electric field components of the state |ψ^(5)(fj)q can display any unequal-power GN Nj-power amplitude squeezing effect.②the any asymmetrical spatial distribution of the classical intensity and the classical amplitude,and the spatial arbitrary distribution characterization of the classical amplitude and the classical initial phase of light field in |ψ^(5)(fj)q would have a direct influence upon the squeezing results and squeezing degree of the unequal-power amplitude squeezing effects presented by the state |ψ^(5)(fj)q. ③the results and conclusions of the GN unequal-power higher-power Nj-power amplitude squeezing of the state |ψ^(5)(fj)q have a theoretical value more generally.
