Description

technical field [0001] The invention relates to a laser discharge glass tube, in particular to an integrated discharge glass tube for an axial fast-flow gas laser. Background technique [0002] The discharge glass tube is one of the core units of the axial fast-flow gas laser, and an anode and a cathode are respectively arranged at the gas inlet and the gas outlet of the discharge glass tube. Once a high voltage is applied between the cathode and anode electrodes, a gas discharge channel will be formed in the discharge glass tube, and the discharge plasma will quickly pass through the discharge area under the action of an external fan, and part of the electric power injected into the discharge plasma will be converted For the laser power output, the other part is converted into heat energy to increase the temperature of the gas. The high-temperature gas generated by the discharge is cooled by a heat exchanger and then recycled to reduce operating costs and obtain higher phot...
