Theory of phase locking of an array of lasers

A theoretical analysis is reported of the radiation produced by an array of periodically distributed lasers with effective coupling between the elements. The coupling is based on the reproduction of the periodic field structure. The possible mode types, losses, and eigenfrequencies are determined for infinite and finite sets of lasers assembled in triangular rectangular arrays. The influence of mirror misalignments, saturation of the active medium, and random phase spread among the individual channels on the modes and their Q-factors is examined.
