1477264 Lasers INTERNATIONAL BUSINESS MACHINES CORP 5 Sept 1975 [19 Dec 1974] 36725/75 Heading H1C A gas laser has a discharge capillary and communicating electrode pockets formed by glass partitions located between and sealed to two glass plates, the electrodes being formed on at least one plate by deposition of a metallic layer such as aluminium. In Fig. 1a the capilliary is formed by a slot 18 extending the length of a glass plate 15, while holes 17 through the plate provide pockets for electrodes 21, 22 deposited on one of two glass cover plates 10, 20. A sealing glass is used to weld the plates together. In a modification, Fig. 2D, the ends of the adjacent plates 30, 31 are ground at Brewsters angle and are sealed by glass plates 45, 451. Cover plate 30 includes a hole 40 extending the electrode pocket 44 in the partitioning plate 31, and a gas fill aperture 36, the hole 40 being sealed by a glass plate 46. The other cover plate is shorter to facilitate mounting of supports 47, 471 carrying adjustable resonator mirrors 48, 481, and is of increased width to expose the terminal tails of the electrodes. In an alternative arrangement, Figs. 3C and 3D, the partitions are formed by glass rods 65-68 attached by frit to cover plates 60, 61. Electrodes 62, 63 formed by a deposition process are provided on one or both cover plates and extend along electrode pockets 72, 73 which are linked by a capillary 70. A modified construction Figs. 3E and 3F, uses a single glass tube 75 to define the capilliary portion, the electrode pockets communicating by openings 80, 81 with the bore of the tube.
