Paper 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.
