Embodiment Construction

[0012] Such as figure 1 , figure 2 As shown, a plane-folded vertical beam combining laser tube includes an air storage tube 1, a return air tube 6, a thin film polarizer 7, a reflective lens 8, and at least four sets of tube components. Each set of tube components passes through the return air tube 6 and the storage tube. The trachea 1 is connected, the at least two sets of tube assemblies are arranged side by side in a first plane, and at least two sets of tube assemblies are arranged side by side in a second plane perpendicular to the first plane, and adjacent tube assemblies in the first plane pass The folded back lens 4 is connected to form a first S-shaped pipeline, and adjacent tube components in the second plane are connected to form a second S-shaped pipeline through the folded back lens 4, and the first S-shaped pipeline and the second S The front and rear ends of the S-shaped pipeline are equipped with coupling lenses 5. In the laser exit direction of the first S-sha...

Abstract

The invention relates to a flatly-foldable vertical beam-combined type laser tube. The flatly-foldable vertical beam-combined type laser tube comprises a gas storage tube, a gas return tube, a film polarizer, a reflecting lens and at least four sets of tube components, wherein each set of tube component is connected with the gas storage tube through the gas return tube; at least two sets of tube components are arranged in the first plane in parallel; at least two sets of tube components are arranged in the second plane perpendicular to the first plane; the adjacent tube components in the first plane are connected through a turn-back lens to enclose a first S-shaped pipeline; and the adjacent tube components in the second plane are connected through a turn-back lens to enclose a second S-shaped pipeline. The flatly-foldable vertical beam-combined type laser tube has the advantages that two beams of strong laser which are generated in the two vertical planes and has the same emergent direction and opposite polarization directions are combined into one beam of laser with high power and high circular polarization degree through the film polarizer and the reflecting lens; the laser beam has high power; facula quality is high; the laser beam is slimmed after being focused; the laser processing speed is high; the laser processing effect is good; and the manufacturing cost is relatively low.

Description

Technical field [0001] The invention relates to a plane folding vertical beam combining laser tube. Background technique [0002] The market potential of carbon dioxide laser tube is huge. In recent years, the market demand has increased geometrically every year. It is widely used in various industries to cut, perforate, engrave, mark, quench, cladding, welding, etc. laser processing. [0003] At present, there are two types of medium and high power laser tubes in the market, one is radio frequency excitation laser (metal tube for short), and the other is axial fast flow laser. The metal tube can meet the market's precision requirements for laser processing, but the price is expensive and the technology is complicated. At present, there are no large-scale industrialized products in China, and they rely heavily on imports. It is difficult to obtain large-scale promotion in China and other developing countries. Especially for high-power metal pipes, only a few companies in developed...
