Phase locking of CO2 waveguide laser arrays of up to 19 channels has been attained by low-loss coupling in a slab waveguide of Talbot imaging dimensions, within a two-mirror cavity. The technique provides strong channel coupling while maintaining a low laser threshold. A seven channel array phase locked into a single mode by this technique has produced 100 W of output and 10% efficiency, demonstrating the effectiveness of Talbot imaging, when combined with confinement in a slab waveguide.
