Features of the dependence of the diffraction efficiency of an acousto-optic Bragg cell with multielement traveling wave transformer on its geometric parameters

Abstract

An equation for calculation of the diffraction efficiency of an acousto-optic Bragg cell with multielement traveling wave transformer taking into account the exponential distribution of the acoustic field along of the transformer is obtained. The results of theoretical and experimental studies of the dependence of the diffraction efficiency of the Bragg cell on the number of radiating elements in the piezoelectric traveling wave transformer are given. Nonlinear behavior of the dependence of the diffraction efficiency on the number of radiators in the considered transformer is analyzed.
