Compact schemes of a multichannel holographic laser system with short-range coupling and increased efficiency of single-mode lasing are developed for low-gain laser media operating not only at the fundamental laser transition but also at other laser transitions of the Nd:YAG crystal. The numerical simulation shows that the maximum possible number of laser channels can be increased by equalising their parameters. The possibility of phase locking of two loop Nd:YAG lasers without a nonreciprocal element with the free-running single-mode lasing efficiency up to 0.64% and the contrast of the interference pattern of the output beams exceeding 0.5 is shown experimentally.
