ABSTRACT:
A gas laser tube is fitted with internal mirrors only and no windows. The laser tube is processed by heating the tube with the ends open in a vacuum oven to drive out contaminating substances. The mirrors are installed by cold welding after the tube has been decontaminated and filled with a fresh supply of its operating gas. The mirrors mount on flexible bellows which enable the mirrors to be easily aligned.
