Efficient phase-locking of 37 fiber amplifiers by phase-intensity mapping in an optimization loop. | LitMetric

Coherent combination of laser beams from 37 fiber amplifiers in a tiled aperture configuration has been achieved thanks to an innovative iterative process. The high efficiency as well as the speed of the phase control demonstrated the relevance of the method for phase locking of a large array of fiber lasers.
