Abstract
A feedthrough structure of a gas discharge laser chamber conducts electric power through the wall of a sealed gas enclosure to a single piece electrode inside the enclosure. The feedthrough structure includes a single piece integrated main insulator larger than the electrode. The main insulator is compressed between the electrode and the wall of the enclosure. The surfaces forming interfaces between the electrode and the single piece insulator are the insulator and the wall are all very smooth to permit the parts to expand and contract as the chamber temperature varies. The feedthrough structure also provides mechanical support and alignment for the electrode and includes seals to prevent gas leakage around the feedthrough structure.
