Coherent beam combination of fiber laser arrays via multiplexed volume Bragg gratings

We report the first experimental demonstration of active coherently combining of fiber laser arrays with multiplexed volume Bragg gratings up to 70W combined output power with diffraction limited beam quality achieved at 82% combining efficiency.
