Abstract

Continuous coupling of square-bore CO₂ waveguide lasers by geometrical overlap in the diagonal direction has been used for phase locking of a five-channel array. A radio-frequency discharge excited device has produced 125 W in phase-locked operation, with power per channel equal to independent single channels. The dependence of phase-locking range on the coupling geometry, and dimensional tolerances has been demonstrated. The array radiates approximately 65% of its power in the axial lobe.
