Abstract

The multimode squeezed state theory is used to analyze and research the effect of both squeezed amplitude and squeezed quantity of equal-power 2m-power Y-squeezing of the generalized electric-field component on multimode functional superposition state light-field upon the injected multimode vacuum field in detail.The findings indicate that the injected multimode vacuum light-field can make the generalized electric-fielcl component of 3MFSS(3 states superposed multimode functional superposition state)light-field appear the Y-sqneezing eggect of 2m-power under the certain condition,can cause the squeezed effect of the quantum light field to build up,and squeezed amplitude to increase,and squeezed degree to deepen.
