OSTI ID:5848035
A hard sealed gas laser tube is described consisting of: an internal electrode structure, envelope means for surrounding the internal electrode structure between first and second fixed flange means for establishing vacuum seals at each end, first and second outside flange means outside the envelope means for engagement with the first and second fixed flange means respectively, means for fastening the first and second outside flange means to the first and second fixed flange means respectively to establish a vacuum seal therewith, the internal electrode structure being inside the envelope means between the first and second fixed flange means, the internal electrode structure including an internal structure flange for coacting with the first fixed flange means for establishing a vacuum seal therewith, the internal electrode structure including at least first and second electrodes for establishing an electric field therebetween, means defining a gas port for allowing gas to flow within the envelope means, cooling means coupled to the internal electrode structure for carrying a coolant to withdraw heat from within the envelope means feedthrough means passing through the internal flange means for establishing electrical connection to at least one of the first and second electrodes, coolant nozzle means carried by the internal flange means for exchanging coolant with the cooling means, total reflecting means and output mirror means for reflecting optical energy, first and second mirror support means in vacuum sealing relationship to the first and second outside flange means, respectively, for supporting the total reflecting means and the output mirror means, respectively, in positions to coact with the internal electrode structure for establishing lasing, and transmitting means including the output mirror means for maintaining a sealed enclosure within the envelope means while transmitting a laser beam therethrough developed within the envelope means.
