Abstract

Laser comprising at least one anode (1) and one cathode (2) for preionization and main discharge, the anode (1) and the cathode (2) having different standard potentials. The laser is distinguished by high reliability and long life. After several hours of operation, practically no material erosion at all is found at the electrodes.
