       The existing glass structure medium-low power carbon dioxide J H 80W 100W 130W 150W laser glass cutting tube usually consists of a collimated discharge tube loaded with a laser working gas, a water-cooled sleeve which is gas-stained and sintered on the periphery of the discharge tube with a water inlet nozzle and a water outlet, and is surrounded by a water-cooling jacket. The gas-tight sintering consists of a gas storage jacket on the water-cooling sleeve and the discharge tube, and the discharge tube and the gas-storage sleeve are connected through the return air tube. The tube is straight in shape, and a cathode tube and an anode tube are arranged at both ends of the venting tube, and a laser total reflection mirror and a laser output mirror are attached to the two ports. This glass-structured straight tubular carbon dioxide J H 80W 100W 130W 150W laser glass cutting tube outputs a laser power of 60 to 70 watts per meter of discharge tube length. The longer the tube, the higher the output power. However, when the length of the pipe exceeds 2 meters, not only the degree of collimation of the discharge tube is not easy to ensure (collimation is one of the main factors affecting the laser spot pattern), the technical operation of glass sintering thermal processing is also more difficult, and packaging, there are many safety hazards in transportation, on-site installation and commissioning, etc., which limits its practical use in many important application areas. In order to overcome the difficulty of the tube being too long and not practical, various laser principle textbooks have an overview of the folding gas laser. The main feature is that on the left and right brackets with the fastening structure installed, according to the designed position A plurality of quartz discharge tubes are mounted and folded, and the optical paths are folded and connected by the mirrors. A laser output mirror, called a laser output window, is attached to the front port of the first discharge tube, and a laser total reflection mirror is attached to the end of the last discharge tube. The left and right brackets and their fasteners are made of micro-expanded alloy Invar or quartz. Although the gas laser of the rigid truss structure solves the problem that the tube is too long, it has some difficult problems to overcome, for example, the structure itself is easily mechanically deformed and the movement is difficult, and thus the spot pattern is unstable. For example, because the pipe material (quartz) and the bracket and the fastener have different expansion coefficients, the laser output power is unstable, the beam quality is not high, and even the stress may cause the tube to burst and break. In actual work, it is difficult to install and use it with other equipment on site. In fact, this kind of rigid truss structure J H 80W 100W 130W 150W laser glass cutting tube has not been promoted.

Two (or more) straight discharge die assemblies are hermetically sealed in a large gas storage sleeve, and the ends of the straight discharge cores are folded end to end through the mirror at the narrow neck extending out of the large gas storage sleeve It is connected with the connecting channel to make a double-core (multi-core) carbon dioxide J H 80W 100W 130W 150W laser glass cutting tube.2 to 20 discharge die assemblies can be installed in a multi-core carbon dioxide J H 80W 100W 130W 150W laser glass cutting tube. There are 24 preferred discharge die assemblies that are folded into a JT shape, a 4N shape, or a W shape by the mirror 14 and the connecting passage 15.The laser output mirror 17 can be made of infrared material such as Ge, Zn Se or GaAs, and the full mirror 16 and the mirror 14 are made of optical glass, silicon or copper polished gold plating; the laser output mirror 17, the mirror 14 and The full mirror 16 is attached with a water-cooling box for water cooling. The cathode can 11 and the anode can 9 can be made of a metal sheet material such as nickel, aluminum, molybdenum, titanium or silver-copper alloy; the anode 10 and the cathode 12 can be d) 1 mm ci) i. 2 mm of pure tungsten. Rod; the metal lead 13 may be a pure nickel strip or a nickel wire.

The glass structure carbon dioxide J H 80W 100W 130W 150W laser glass cutting tube of the utility model has the advantages of simple structure, reasonable design and strong practicability. Of course, the production process is strict and the technical content is high, but it can be produced in batches. As a preference, a double-core structure is recommended, which can produce a tube with an output power of 190 watts to 230 watts in a total length of 1.8 2 m. The laser power is stable, the spot pattern is good, the life is long, and the installation and debugging are convenient in the field. It can not only improve the working efficiency of the original production process but also solve the problem of thick material cutting that cannot be solved by the original process. It can be widely used in leather cutting, acrylic cutting, die-cutting and other high-demand laser cutting and laser engraving industries, with wide practicality and broad market prospects. The laser output mirror 17, the mirror 14 and the total reflection mirror 16 are all attached with a water-cooling box for water cooling. The structure of the one-tube double-core carbon dioxide J H 80W 100W 130W 150W laser glass cutting tube is further such that a cathode tube 11 and an anode tube 9 are respectively disposed at both ends of the discharge tube 2, and a discharge activation region is formed between the cathode tube 11 and the anode tube 9. The cathode can 11 and the anode can 9 are made of a metal material such as nickel (Ni), aluminum (Al), molybdenum (Mo), titanium (T I), or silver-copper alloy (Ag Cu). The anode can 9 and the cathode can 11 are electrically connected to the anode 10 and the cathode 12, respectively, which are fixed to the side walls of the neck of the discharge tube by metal leads 13, and the metal leads 13 may be made of pure nickel tape (wire). The anode 10 and the cathode 12 are made of CH mm-(M.2mm pure tungsten rod, which can be sintered into a tungsten rod glass ball by a transition glass to be sintered on the side wall of the discharge tube neck 18 of the discharge tube 2, or The anode 10 and the cathode 12, which are the terminals of the discharge tube 2, are respectively connected to respective DC power sources, and the two discharge tubes 2 are respectively energized by synchronous discharge excitation. Embodiment 2 Multicore of the present invention The structure of the carbon dioxide J H 80W 100W 130W 150W laser glass cutting tube is the same as that of the double-core carbon dioxide J H 80W 100W 130W 150W  laser glass cutting tube of the present invention, except that a plurality of discharge die assemblies are hermetically sintered in a large gas storage sleeve 1, and each discharge tube 2 passes through the connection channel in turn. 15 and the mirror 14 are folded and connected to realize the serial connection, and the mirror 14 is sealed at the folding corner of the connecting channel 15 to fold the optical path. When the discharge die assembly is three, each of the discharge tubes 2 can be folded into an N shape; When the number of core components is four, each of the discharge tubes 2 can be folded into a W shape; when more discharges are used for the die assembly, by analogy.
