Abstract

It is constructed that three-state-superposition multimode Functional Superposition state light-field |ψ(IR)0(αj〉q with injected multimode vacuum field along X direction spreading in the gain medium and absorb medium.The multimode squeezed state theory is used to system research the effect of equal-power high-power amplitude-squeezing of the generalized electric-field component on |ψ(IR)0(αj)〉q state,then the influences of the gain and absorb spoilage effect of medium to equal-power amplitude-squeezing of the generalized electric-field component are analyzed in detail.It is pointed out that both the squeezed amplitude and the squeezed intensity of amplitude-squeezing mentioned above will diminish within the gain medium;both the squeezed amplitude and the squeezed intensity of amplitude-squeezing will increase if coefficient |αj| is increase within the absorb spoilage medium,and absorption effect is increasingly strong,then the squeezed amplitude and the squeezed intensity is increasingly big.
