    Abstract: A method of sealing a metallic wire between two vitreous parts. The wire is positioned so that its ends extend outwardly from opposite sides of the enclosure formed by the parts. The adjacent side edges of the parts are formed with protuberent lips which surround the portion of the wire adjacent one end thereof. The parts are preheated, in a controlled atmosphere. A laser beam is then focused on the one end of the wire to fuse it and thereby also fuse, by contact heat transfer, the side portions of the vitreous parts which are adjacent the wire. The wire is thus welded in the enclosure with the fused protuberent lips forming an outwardly extending enclosure portion which reinforces the seal in the area adjacent to the fused wire.

    Abstract: A gas laser comprises an outer tube and a plurality of graphic and ceramic rings placed inside the tube. The rings are in the form of a stack which is blocked on one end by lugs welded to the inner surface of the tube. The other end of the stack emerges into a free space formed by an enlarged area arranged in the inner surface of the tube and is held by a disc which is biased against lugs placed on the inner surface of the enlargement.
