20120236897 | STRIPLINE LASER - 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. | 09-20-2012 |
20130329763 | CORROSION RESISTANT ELECTRODES FOR LASER CHAMBERS - Corrosion resistant electrodes are formed of brass that has been doped with phosphorus. The electrodes are formed of brass that contains about 100 ppm to about 1,000 ppm of phosphorus, and the brass has no visible microporosity at a magnification of 400×. The brass may be cartridge brass that contains about 30 weight percent of zinc and the balance copper. Corrosion resistant electrodes also may be formed by subjecting brass to severe plastic deformation to increase the resistance of the brass to plasma corrosion. The corrosion resistant electrodes can be used in laser systems to generate laser light. | 12-12-2013 |
