Abstract

Apparatus for producing laser radiation which includes a pair of discharge electrodes for firing a gas discharge which extends transversely with respect to the axis of the laser resonator, wherein pre-ionization is produced by a corona discharge, a charging-and-discharging circuit and a gas circulating-and-cooling system. The first electrode is secured to the wall of the gas chamber which is made from non-conducting material, wherein the securing elements serve as current supply means. The second electrode is mounted to the same wall as the first electrode on a plurality of metal rods. Such metal rods simultaneously provide the mechanical support function and the electrical current supply, and, at least in the region of the gas chamber, are surrounded by an insulator tube having a high dielectric constant so that a corona discharge can be produced between the first electrode and the insulated metal rods.
