Paper Abstract

A wide-aperture, single-mode TEA-CO2 laser has been developed using a graded-reflectivity mirror to discriminate against higher-order modes. The laser frequency was stabilized by an active cavity-length control plus injection from a low-pressure, CW CO2 laser. The use of a graded-reflectivity output coupler allowed discrimination against higher-order transverse modes while producing a near diffraction limited far-field beam pattern. Because the transverse mode dimension is large, the frequency "chirp" was low.
