Abstract:
The acousto-optical interactions of Bessel and Gaussian light beams with the ultrasonic field in liquids under the condition of Raman-Nath diffraction for the standing-wave mode are experimentally investigated. The main differences of acousto-optical interactions for Bessel and Gaussian light beams are revealed. The various phenomena of refraction and focusing of Bessel beam in liquids owing to sound-field spatial modulation are demonstrated.
