Abstract

Waveguide structures have become one of the most commonly used gas laser structures in many applications. Especially among different waveguide gas laser, CO₂ lasers have been extensively investigated theoretically as well as experimentally (see, for example, [1] and its references). One of the most important problems which appear in analysis of waveguide lasers is quantity of generated output beam. However using Gaussian reflectivity mirror as transmission one make possible improve quantity of the beam.
