A means for producing uniform discharges in carbon dioxide (CO.sub.2) transversely excited atmospheric (TEA) lasers by the utilization of a fine wire as the central (cathode) electrode coaxially disposed in a cylindrical outer (anode) electrode having a diameter selectively chosen to provide a large ratio of outer to inner electrode radii which as a consequence produces a radial gain profile which is well localized in the center of the discharge tube and accordingly allows for efficient matching of low order stable optical modes to the active gain region while providing a high degree of mode selectivity in favor of these modes.
