Abstract
A triple point screen which electrically insulates the high voltage electrode in the discharge region of a gas discharge laser system. The screen is formed from an inorganic dielectric to withstand the corrosive atmosphere of the gas discharge laser. The triple point screen has a grounded conductive metal screen molded into the dielectric and positioned close to the triple point of the anode to substantially reduce the strength of the electric fields at the triple point.
