Binary gratings were used to achieve coherent beam summation at 1.06 micrometers using diode-laser-pumped Nd:YAG ring lasers. Mutual coherence of two such devices was achieved by optical injection locking. This is believed to be the first demonstration of cw injection locking of solid-state lasers other than semiconductor diode lasers. The two sources were combined, both free-running and phase-locked, while varying the phase of one source at the grating. The results show very efficient beam summation in a configuration that could be used to combine a large number of individual lasers.
