Abstract

Two independent He–Ne lasers operating at 0.6328 μm were phase locked to a very high degree of coherence using feedback control. One of these lasers was single mode and the other multimode. The results suggest that the present technique can be used to generate high-power, coherent light pulses from an array of He–Ne lasers.
