摘要： A gas laser apparatus in which a gas medium in a case and a lubricant for bearings supporting a blower for circulating the gas medium are isolated from each other, so that the lubricant can be prevented from mixing into the gas medium while no substantially large resistance is applied to the blower drive. To isolate the gas medium and the lubricant, magnetic fluid shaft seals (10, 11) are used for sealing between the lubricant for the bearings (6) for supporting rotation shafts (3a, 3b) of the blower (3) and the gas medium in the case (1).

摘要： A film is formed on the discharge parts of the main discharge electrodes. In order to prevent erosion of the discharge parts by the halogen gas contained in the laser gas, a substance that tends not to react with the halogen gas, i.e., a halogen-resistant substance, is used for this film. Furthermore, in order to prevent deformation of the discharge parts by the bombardment and heat of the main discharge, a substance that has a higher hardness than the metal of the main discharge electrodes or a substance that has a higher melting point than the metal of the main discharge electrodes is used for this film. As a result, deterioration of the electrodes can be inhibited, so that a stable laser output can be obtained, and the replacement interval of the electrodes can be extended.
