ABSTRACT:
A method for producing high peak energy radiation from a gaseous lasing medium excited by a main electric discharge which is transverse to the laser beam path. The main electric discharge current flows between elongated copper main electrodes positioned on opposite sides of the laser path and follows a pre-ionizing discharge between a plurality of copper elements positioned adjacent the optical path. The pre-ionizing discharge is selected in time and intensity to produce a gradation of temperatures along a thin layer of copper oxide formed on the copper elements and catalytically aiding in rapid recombination of carbon monoxide with the free oxygen which is produced by the discharge between the main electrodes.
