           As the range of 1280 80w carbon dioxide glass laser tube for laser cutting machine continues to expand, the requirements for the output power of 1280 80w carbon dioxide glass laser tube for laser cutting machine are also increasing, especially at output powers above 200W. However, the 250-500W carbon dioxide laser tube is still a blank in China. In order to increase the output power of the 1280 80w carbon dioxide glass laser tube for laser cutting machine , it is necessary to increase the length of the discharge tube. However, when the length of the discharge tube is increased to more than 2 meters, not only is it extremely difficult to use in actual use, but the output light is also unstable. At present, the technical problem is mainly solved by folding a plurality of discharge tubes, and the specification discloses a multi-core 1280 80w carbon dioxide glass laser tube for laser cutting machine , which solves the above technical problems, and adopts a technical solution of two or more straight discharge tube assemblies. The gas seal is installed in a large gas storage pipe. The two ends of the straight discharge die are folded end by end through a mirror and a connecting passage at a narrow neck extending from the large gas storage pipe to form a double-core or multi-core1280 80w carbon dioxide glass laser tube for laser cutting machine . Because the discharge tubes are connected through the connecting channels, that is, the connecting tubes are connected, the manufacturing process is difficult, the tube blank is not easy to manufacture, and the laser output power is unstable due to the large bending and bending of the connecting channels, and the beam quality is low, even the light path is tortuous and the tube is broken and scrapped. Therefore, a new technical solution is needed to solve the above technical problems.An all-glass structure double-core 1280 80w carbon dioxide glass laser tube for laser cutting machine  with compact structure, reasonable design, high laser output power and high beam quality is provided. The technical solution adopted is: an all-glass structure double-core 1280 80w carbon dioxide glass laser tube for laser cutting machine , comprising a gas storage tube and two sets of discharge discharge die assemblies arranged in parallel, the two sets of discharge die assemblies being a first discharge die assembly and a second discharge die assembly, respectively The two sets of discharge die assemblies each include a discharge tube and a water-cooled sleeve that is gas-tightly sintered outside the discharge tube, and the water-cooled sleeve is provided with a water inlet and a water outlet, and the front end outer wall of the two groups of water-cooled sleeves Each of the two sets of discharge tubes is respectively provided with a cathode tube and an anode tube, and a discharge tube is formed between the cathode tube and the anode tube in each of the two groups of discharge tubes, wherein the return tube is connected to the gas storage tube. The cathode barrel and the anode barrel are respectively electrically connected to a cathode and an anode fixed on sidewalls of both ends of the discharge tube by metal leads, and the two sets of discharge die assemblies are disposed in the gas storage tube, and the first discharge tube core The front end of the assembly is provided with an output lens holder extending from the gas storage tube, the output lens holder is provided with an output lens, and the front end of the second discharge die assembly is provided with a mirror holder extending from the gas storage tube, a reflector lens is disposed on the lens holder, the rear end of the gas storage tube is an arched structure, and two holes are blown on the arched outer wall of the gas storage tube, and the two holes are sealed and provided with a fold A reflective lens that refracts the optical paths of the two sets of discharge die assemblies. The two return air pipe phases are dislocated on the water-cooling casing. The inner walls of the two sets of discharge tubes are coated with a binary coating made of rare earth metal wire, and the power and stability of the 1280 80w carbon dioxide glass laser tube for laser cutting machine are increased by the binary coating. The utility model has the rear end of the gas storage pipe designed as an arch structure, and two holes are blown on the arched outer wall of the gas storage pipe with respect to the two discharge tubes, and the double reflection holes are sealed on the two holes, and the two-folded lens is sealed The reflective lens connects the optical paths of the two discharge die assemblies to form a laser cavity, which improves the stability and output power of the beam transmission. At the same time, the two sets of discharge die assemblies are placed in the gas storage pipe to achieve the purpose of optical path turning in the gas storage pipe, the spot pattern is enhanced, and the connecting pipe is omitted, and the output power can reach 250 W or more within 2 m total length. Achieve high power output to meet the requirements of different industries. 

           The stability and output power of the transmission, the two sets of discharge die assemblies are placed in the gas storage tube 5, the front end of the first discharge die assembly is provided with an output lens holder extending out of the gas storage tube, and the output lens holder is provided with an output lens 1. The front end of the second discharge die assembly is provided with a mirror holder extending from the gas storage tube, the mirror holder is provided with a reflection lens 14, and the rear end of the gas storage tube 5 is designed as an arch structure, in the gas storage tube 5 Two holes are blown on the arched outer wall relative to the two discharge tubes 4, and the baffle mirrors 10 are sealed on both holes, and the optical paths of the two discharge die assemblies are communicated by the two-fold reflecting mirrors to form a laser cavity. Meanwhile, in order to further enhance the output power, the stability of the output power, and the service life, the inner walls of the two sets of discharge tubes 4 are coated with a binary coating 7 made of a rare earth metal wire. The utility model has the above structural design, which can be completely fired from the glass material, and has the advantages of simple manufacturing process, low production cost and convenient industrial production. Compared with the existing high-power folded carbon dioxide laser tube, it achieves the purpose of achieving optical path reversal in the gas storage tube, and the connection tube is omitted, the manufacturing difficulty is reduced, the output power and stability of the laser are improved, and the output thereof is improved. The power can be more than 250W in the total length of 2m. At the same time, after the binary coating is applied on the inner wall of the discharge tube, the output power can reach about 300W, which is much higher than the existing high-power folded carbon dioxide laser tube.
