ABSTRACT:
An in-phase coupled strip linear CO.sub.2 waveguide laser includes an upper aluminum plate and an aluminum waveguide bed including parallel ridges, each in the range of about 2 to about 5 mm wide, at a gap of about 0.5 to 2 mm from the upper plate. The slots are about 2 mm deep to prevent discharge therein and about 1 mm wide. The width of the slots is selected to permit coupling between the discharge channels formed between each ridge and the upper plate while separating the discharge beams in each channel. Discharge in each channel is in-phase coupled in the fundamental mode to produce a single lobe far field with a simple Fabry-Perot resonator.
