摘　　要：构造了第Ⅰ种强度不等的非对称三态叠加多模叠加态光场ψ(ABC)1〉q.利用多模压缩态理论,讨论了态ψ(ABC)1〉q的第二正交分量即电场分量的高次和压缩(N次方H压缩)特性.结果发现:⑴当各模的强度和初始相位各不相等时,在一定条件下,态ψ(ABC)1〉q的电场分量可呈现出周期性变化的任意等幂次的高次和压缩效应.⑵当各模的强度和初始相位相等时,态ψ(ABC)1〉q的第二正交分量的高次和压缩现象消失,且恒处于N-H最小测不准态.A new type of multimode superposition state light field ψ(ABC)1>q is constructed, which is made of the macroscopically distinct three different multimode coherent states with unsymmetry and unequalintensity. The properties of highpower sumsqueezing of the electric component are studied in detail by utilizing the multimode squeezed state theory. It is found that: ⑴ under the conditions of unequal intensity of each mode, the electric component of state ψ(ABC)1>q can produce any highpower sumsqueezing effects; ⑵ under the conditions of equalintensity of each mode, the squeezing effects disappear, and the state ψ(ABC)1>q can only stay in the NH minimum uncertainty state.
