Abstract

Interference of two femtosecond laser beams is a synchronous ultrasonic Bragg grating is studied experimentally. Initial phase of the ultrasound affects the interference pattern and energy distribution between two output beams. This phenomenon can be used for controlled coherent combining of two beams using a single Bragg cell.
