Abstract

A gas laser is excited by means of a high voltage discharge, at least one firing pulse being applied to a gas discharge tube. The firing pulse can be initiated by a release signal which is applied to an electronic firing unit. Firing pulses then applied to the gas discharge tube until a check-back signal concerning the successful firing of the gas discharge tube is supplied to the electronic firing unit by a detector unit which monitors the operating state of the gas discharge tube.
