摘要： A discharge tube structure of a gas laser generator has end common vessels at its both end sections and an intermediate common vessel at its intermediate section. The end common vessels and intermediate common vessel are connected through the first and second cooling ducts to a centrifugal blower, which is provided at its center the first communicating port communicating with the first cooling duct and at least two second communicating ports communicating with the second cooling ducts opposed to each other with respect to the first communicating port. The simplified second cooling ducts allows the mixture gas to be supplied smoothly to the intermediate common vessel, thereby increasing the laser output.

摘要： A gas laser has an electrode of improved construction. The electrode, for example a cathode, comprises an inner cathode and at least an outer cathode spaced from the inner cathode and disposed on the side thereof away from to an anode. Each of the cathodes has a central hole from which glow discharge is formed, and the outer cathode further has a plurality of through-holes around the central hole. A gas medium flowing in a discharge tube passes through the central hole of the inner cathode via the central hole and through-holes of the outer cathode. The gas medium forcedly enters the glow discharge from the inner cathode thereby to cause it expand and a part of the gas medium having passed through the through-holes of the outer cathode squeeze the glow discharge from the outer cathode so that the glow discharge can enter the glow discharge from the inner cathode. Therefore, the current density of the glow discharge in the discharge tube is made information.
