Yang Zhi-yong · 2005
By utilizing the theory of multimode squeezed state,the characteristics of generalized nonlinear equal-power amplitude squeezing of the multimode functional even coherent state is studied,and it is found, when the squeezed number is an odd number,the two quadrature components of the state can present symmetry equal-power amplitude squeezing effect,the squeezed degree,the squeezed depth and the squeezed amplitude are related intensively to the squeezed number,the superposition probability, the classical intensity and initial phase of each mode of the state and other parameters.The further research shown that the conclusions are not completely the same as the theoretical results if the classical intensity of the two three light-fields of the multimode functional even coherent state according to ground mode circular Gaussian distribution.
