Abstract

A device for capacitive coupling of HF energy to a laser section has a capacitor situated in the input line, first and second capacitor electrodes, a dielectric situated between them and first and second cooled contact electrodes embracing a dielectric laser tube. The first cooled contact electrode has a surface with a partial region that comprises the first capacitor electrode. A dielectric foil is situated on the partial region and forms the dielectric of the capacitor. And an electric conducting web is situated on the foil and forms the second capacitor electrode.
