Abstract
A gas laser discharge unit is provided. The discharge unit includes an elongated electrode plate having a plurality of spaced-apart holes therein and a plurality of coaxial high voltage ducts. Each duct extends through one of the holes in the electrode plate and includes a central conductive core and an insulator element arranged around the core to electrically insulate said core from the electrode plate. An elongated high voltage electrode is electrically connected to the cores of the ducts. In addition, an elongated ground electrode is positioned to oppose the high voltage electrode and form a gas discharge gap therebetween. The ground electrode is electrically connected to the electrode plate. The gas laser discharge unit may be removably mounted as a module into a gas laser tube, such as an excimer laser tube.
