Abstract

Theoretical predictions of the acousto-optic interaction under Raman–Nath conditions of ultrasound and laser light with a beam width w comparable to or smaller than the ultrasonic wavelength Λ are experimentally investigated, and good agreement between experiment and prediction is found. The experimental setup consists of a pulsed laser, emitting pulses that are synchronized with the sound frequency by means of a controllable delay time. When wΛ, strong focusing is obtained for most delay times. The lensing properties of this configuration are carefully investigated.
