FIELD: power industry.SUBSTANCE: invention relates to laser engineering. The gas laser discharge system contains the extended first and second laser electrodes, located in the laser housing, UF pre-ionizer located aside from one of laser electrodes and designed as the system of ignition of sliding discharge between extended igniting electrode and additional electrode located on the surface of the dielectric layer coating an extended metal substrate. The dielectric layer is designed as a part of direct thin-walled cylindrical tube enclosed between two planes of the tube cuts made along its length parallel to the axis. The igniting electrode is placed on the internal surface of the part of the dielectric tube along it and connected to the laser electrode, and the surface of the extended metal substrate is made concave and superposed with the part of external cylindrical surface of the dielectric layer.EFFECT: possibility of increase of generation energy and simplification of the laser design.4 cl, 4 dwg |
