Abstract
Abstract In a discharge structure for a gas laser having electrodes for the production of a gas discharge, wherein on a section of the discharge container of insulating material, a resistance layer is applied which forms a current-limiting resistor, and in which the section carrying the resistance layer is an arbitrary shortcircuit and breakdown-proof wall portion of the discharge container.
