Abstract

Two modes corresponding to wideband acousto-optic interaction have been revealed based on the analysis of Bragg conditions. The moduli of the electric fields of the incident and diffracted light beams are calculated for one of these modes. The half-power frequency bandwidth of the control signal at a level of diffracted beam was found to be 495 MHz for the light wavelength λ0 = 632 nm at a diffraction efficiency of 2.2% on an average ultrasonic frequency of 3.27 GHz.
