Abstract

Several papers contain calculated optical losses of CO₂ waveguide resonators considering attenuation and coupling losses due to interference between modes within the space between the end of the waveguide and the mirror. A strong dependence of these losses on guide dimensions, especially those dimensions affecting the Fresnel number of the resonator, was found. To measure these losses we used a method based on a scanning Fabry-Perot interferometer. By determining the bandwidth total losses are calculated.
