In a flow channel for a transverse flow gas laser with electrodes arranged in opposite walls of the channel for transversal high- frequency excitation, which walls consist of dielectric material on the side facing the channel, which material carries a metal coating on its side facing away from the channel, the metal coatings in each case being connected to a pole of a voltage source, in order to achieve a mechanically rugged design even with large widths, it is proposed that the channel surrounded by a supporting housing which has a mounting surface for the electrodes on each of the walls holding the electrodes, the dielectric material is designed as a support, and the metal coating of each electrode is surrounded with a sealing edge opposite which the metal coating is pushed back in the direction of the interior of the channel, that the dielectric support with its sealing edge abuts in a sealing manner on the mounting surface of the housing and is held in this position on the housing, and that the metallic coating on its side facing away from the dielectric support is exposed. <IMAGE> |
