Paper Abstract

In 1964, Marcatili and Schmeltzer proposed the use of hollow dielectric waveguides as low-loss components for laser amplifiers [1]. Early workers on waveguide lasers sought definite gain/bandwidth advantages. Nowadays waveguide structures are one of the most commonly used gas laser structures in many applications. Especially among different waveguide gas laser, CO2 laser are extensively investigated theoretically as well experimentally (see Ref.2 and its references). That kind of lasers can run at much highei pressures than conventional Gaussian-resonator lasers, and thus offered increased frequency tenability. 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.
