Water-cooled gas laser tube

Abstract

The invention relates to a gas laser tube. A water-cooled gas laser tube comprises a discharge tube, a cathode electrode, an anode electrode, a reflecting mirror, an output mirror, a metal supporting frame, an insulated anode electrode chamber and a cathode electrode chamber. The anode electrode chamber is connected at one end of the metal supporting frame, and the cathode electrode chamber is connected at the other end of the metal supporting frame. The metal supporting frame is provided with a cooling chamber and a gas storage chamber. The cooling chamber extends in the extension direction of the discharge tube, and the gas storage chamber is communicated with both the anode electrode chamber and the cathode electrode chamber. The discharge tube penetrates through the cooling chamber and communicates the anode electrode chamber with the cathode electrode chamber together , the two ends of the discharge tube are connected with the cooling chamber in a sealing mode, a water inlet is formed at one end of the cooling chamber, a water outlet is formed at the other end of the cooling chamber, the reflecting mirror and the anode electrode are located in the anode electrode chamber, the output mirror and the cathode electrode are located in the cathode electrode chamber. The water-cooled gas laser tube can be conveniently recycled and reused and solves the problems that an existing laser tube of a glass structure can be easily broken to caused losses to clients, is inconveniently to recycle and reuse and a large amount of harmful gas can be generated in the process of production.

Description

technical field [0001] The invention relates to a gas laser tube, in particular to a water-cooled gas laser tube. Background technique [0002] The existing gas laser tubes are all in the form of a sealed structure, that is, including a discharge tube, a water-cooled tube sleeved outside the discharge tube, a gas storage tube sleeved outside the water-cooled tube, electrodes and resonant cavity mirrors (including reflectors and Output mirror), the discharge tube, water cooling tube and gas storage tube are all glass tubes, the water cooling tube and the discharge tube, and the discharge tube and the gas storage tube are all welded together by high-temperature flame firing to form a cooling chamber and a gas storage tube The gas storage chamber communicates with both ends of the discharge tube, and the gas storage chamber is filled with laser gas. [0003] The existing gas laser tubes have the following disadvantages: since the glass tubes are connected together by sinte...
