Abstract: The conditions of phase locking of a three-channel holographic Nd:YAG laser system based on self-pumped phase-conjugate oscillators emitting giant 100-mJ, 60-ns monopulses in each of the channels are investigated experimentally. The pulse-to-pulse stable self-phase-locking of the laser system with a pulse repetition rate up to 20 Hz is obtained. The mutual coherence of laser channels was increased up to 0.87 by separating the controlling channel which initiates lasing in a set of controllable channels generating synchronous monopulses.
