Abstract
A quartz laser tube for use with a metal, or metal halide, laser media employs a coaxial electrical connection in which a longitudinal discharge in the laser medium serves as the central conductor, and the ground return path is a cylindrical metal container which surrounds the laser discharge. This arrangement minimizes the circuit inductance for a given longitudinal discharge, and the outer metal cylinder serves both as a heat shield and a ground shield for reducing electrical noise radiation. Optical access in the longitudinal direction is provided by cylindrically-symmetrical electrode/window assemblies attached to either end of the quartz laser discharge tube.
