Adaptive optical system based on the Gerchberg-Saxton algorithm for phase locking of single-mode laser radiators

A method for active phase locking of laser sources in a multichannel laser system based on the Gerchberg-Saxton algorithm is considered. A global optimization-based strategy for retrieving phase information is proposed. The system is simulated numerically for a different number of phased channels.
