Abstract
A laser head comprising a tube having a wall with the configuration of a hollow cylinder. A first ring flange extends radially generally outwardly of the tube wall at one end and is connected to the tube by a single continuous weld. A second plate flange is disposed at the same end and extends generally axially of the first flange. The first flange is coupled to the second flange and sandwiches a metal gasket therebetween to form a pressure seal. An electrode assembly is mounted to the second plate flange and at least one high voltage discharge feed extends through the wall of the tube to energize the electrode assembly. The tube is formed of a homogeneous metal that is free of any surface plating and is less reactive with Halogen gas than pure aluminum. In an associated method, the interior surface of the tube is polished to reduce the surface area and inhibit the entrapment of water vapor.
