Abstract
In a stripline laser, a gas mixture containing carbon dioxide is situated as a laser-active medium between two plate-type electrodes lying with their flat sides opposite one another. The electrodes define a discharge space, at whose end sides lying opposite one another a resonator mirror is respectively arranged. The resonator mirrors form an unstable resonator. To operate the stripline laser in the 9.3 μm band and/or in the 9.6 μm band, the electrodes are provided with a passivation layer on their flat sides. The passivation layer, of at least one electrode, contains silicon dioxide in a region covering a partial area of a flat side. A distance between the electrodes is set such that the attenuation of laser beams in the 10.3 μm band and in the 10.6 μm band is greater than the attenuation of laser beams in the 9.3 μm band and/or in the 9.6 μm band.
