Oscillation dynamics of a phase-locked three-channel holographic Nd:YAG laser system

A method of phase locking of a parallel multichannel laser system by holographic gain gratings in the active laser medium at a long-range holographic coupling of laser channels is developed. The oscillation dynamics of a three-channel holographic Nd:YAG laser system is simulated by considering the phase-locking conditions depending on the relative gain mismatch in laser channels. The conditions of lasing with the gain-selected control laser channel are found under which controlled channels are phase-locked even in the case of the threefold difference in their gains.
