       Combined 300w 400w 500w 600w 800w 1000w CO2 laser tube manufacturing method.Due to the irreplaceability of non-metallic materials processing, 300w 400w 500w 600w 800w 1000w CO2 laser tube have great market potential, especially for medium and high-power 300w 400w 500w 600w 800w 1000w CO2 laser tube. In recent years, market demand has increased by several times per year. At present, there are three types of medium and high power 300w 400w 500w 600w 800w 1000w CO2 laser tube on the market: one type is RF excitation lasers, which are expensive and complicated in technology. Only a few companies in the US and Germany can produce them; the second category is axial-block lasers, due to their production processes and technologies. The reason for the route is that only high power has the cost performance and competitive advantage, and the cost of use is also high. The third type is the folded CO2 medium power laser tube made of pure glass. Due to the glass characteristics, its stability is not good. It has also failed to break through kilowatts of power, and there is still some distance from the market demand.

     The existing folding laser tube has poor stability and is not easy to output higher power, and provides a combined 300w 400w 500w 600w 800w 1000w CO2 laser tube with high stability and high-power laser. In order to solve the above technical problem, the technical solution adopted by the present invention is: a combined 300w 400w 500w 600w 800w 1000w CO2 laser tube including an air storage tube, the gas storage tube is provided with a full mirror holder and a window mirror seat, and the full mirror holder has The total reflection cavity has a window cavity, and the total reflection cavity and the window cavity are connected by a plurality of discharge tubes connected end to end in sequence, and a folding mirror holder is arranged between the adjacent two discharge tubes, and the folding mirror holder has a folding cavity. A first mirror and a second mirror are mounted in the folding chamber, and the first mirror cooperates with the second mirror to reflect the laser light emitted from the previous discharge tube into the next discharge tube, and the total reflection chamber is directly mounted a total reflection mirror of the discharge tube is connected, and a window coupling lens facing the connected discharge tube is installed in the window cavity, and each of the discharge tubes is respectively placed in a water-cooled tube, and both ends of the water-cooled tube have inlet and outlet nozzles respectively The two ends of the discharge tube are respectively provided with connecting members for connecting the folding back chamber, the total reflection chamber or the window chamber, the connecting member at one end of the discharge tube is provided with a positive electrode, and the connecting member at the other end is provided with a negative electrode, a positive electrode and Negative The gas is uniformly connected to the discharge tube, and the total reflection chamber, the folding chamber and the window chamber are respectively connected to the gas storage tube through the gas return tube, and the gas storage tube is provided with an exhaust port. Preferably, the two ends of the connecting member are respectively provided with a sealing ring, and the connecting member is connected to the discharge tube, the total reflection chamber, the folding back chamber or the window cavity through the sealing ring. Preferably, in the above solution, the full mirror mount is provided with a total mirror mounting port that communicates with the total reflection cavity, the total reflection mirror is bonded to the total mirror mounting port, and the window mirror holder is provided with a window coupling connecting the window cavity. a lens mounting port, the window coupling lens is bonded to the window coupling lens mounting opening, the folding mirror holder is provided with a first mirror mounting port and a second mirror mounting port connecting the folding cavity, and the first mirror is bonded to the first reflection At the mirror mounting opening, the second mirror is bonded to the second mirror mounting opening. Preferably, the gas storage tube, the full mirror holder, the window mirror holder, and the folding mirror holder are integrally molded by quartz glass, and the discharge tube and the water-cooling tube are integrally molded by ordinary glass firing.

As a preferred aspect of the above aspect, the connecting member is made of metal. Combined300w 400w 500w 600w 800w 1000w CO2 laser tube, the discharge tube adopts ordinary glass fired discharge tube with good straightness and easy to cool; various optical lenses are attached to the mirror base of quartz glass fired into a whole structure, which is not easy to be produced when the laser tube works. The deformation, which greatly improves the stability of the entire laser, also provides a prerequisite for improving the quality of the optical spot, and the ability to use more root discharge tubes provides a prerequisite for improving the laser power. The seat 3 is provided with a window coupling lens mounting opening 33 that communicates with the window cavity 31. The window coupling lens 32 is bonded to the window coupling lens mounting opening 33. The folding mirror base 5 is provided with a first mirror mounting opening 54 that communicates with the folding back cavity 51 and the second mirror mounting opening 55 is bonded to the first mirror mounting opening 54 and the second mirror 53 is bonded to the second mirror mounting opening 55. The gas storage tube 1, the full mirror holder 2, the window mirror holder 3, and the folding mirror holder 5 are integrally molded by quartz glass, and the discharge tube 4 and the water-cooling tube 41 are integrally molded by ordinary glass firing. The quartz glass has the advantages of high melting point and extremely low thermal deformation coefficient, so that the gas storage tube 1, the full mirror holder 2, the window mirror holder 3, and the folding mirror holder 5 are not easily deformed when the laser works. The utility model utilizes the advantages that the ordinary glass has a low melting point and is easy to straighten, and the ordinary glass has a high relative thermal conductivity and is easy to discharge.

The first mirror 52 and the second mirror 53 are respectively attached to the first mirror mounting opening 54 and the second mirror mounting opening 55 on the folding mirror base at an appropriate angle so that the axes of the plurality of discharge tubes 4 are respectively the hearts are optically connected in a straight line. The total reflection mirror 22 is attached to the total reflection lens mounting opening 23 on the mirror housing 2, and the window coupling lens 32 is attached to the window coupling lens mounting opening 33 on the window mirror base 3, and the total reflection mirror 22 and the window coupling mirror are attached. 32 is perpendicular to the axis of the discharge tube 4, respectively. After the gas storage pipe 1 is evacuated through the exhaust port 12, it is charged with a CO2 laser working gas, and a high-power CO2 laser is generated under the excitation of a high-voltage DC power source.

       The preferred embodiments of the present invention have been described in detail above, and it is understood that those skilled in the art can make various modifications and changes in accordance with the inventive concept without departing from the scope of the invention. Concepts of the Invention The technical solutions that can be obtained by logic analysis, reasoning or limited experiments on the basis of the prior art are all within the scope of protection determined by the claims.
