Paper Abstract

We propose a novel method for reducing the spatial coherence of a laser beam by sound-light interactions. Use is made of a combination of Bragg diffraction and Raman-Nath diffraction in an acousto-optic deflector. Applications in beam splitting, beam profile shaping, and generation of highly directional, partially coherent wavefields are dis- cussed and demonstrated.
