Problems solved by technology

[0003] In order to overcome the fact that the carbon dioxide laser tube is easily decomposed during operation, thereby changing the type and proportion of the working gas in the laser tube, the oxygen produced by the decomposition of carbon dioxide is easier to mix with the metal coaxial electrode in the laser tube and the working gas N 2 The reaction occurs, which aggravates the change of the working gas composition in the laser tube; and the sputtering produced by the coaxial electrode in the glow discharge absorbs a large amount of working gas, and at the same time, the sputtering will pollute the total reflection mirror and the output mirror.

Abstract

The related sealing-type CO2 laser tube comprises: a metal-plated full reflection mirror 1, a muffler 2 set in tube 4 to connect sheath 3 and tube 5, a gas storage sheath 3, a water cooling tube 4 set on top of a discharge tube 5 together in sheath 3, an output mirror 6 together with mirror 1 bonded on ends of laser tube ends by epoxy resin, the TiO2 photo catalyst 8 coated on inner wall of tube 5 and electrodes 7 / 9, and two electrodes 7 / 9 coaxial arranged on ends of tube 5. This invention is simple and convenient, prolongs product life time, reduces cost, and has well social and economic benefits.

Description

Technical field: [0001] The invention relates to an improved invention of a sealed-off carbon dioxide laser tube, in particular to the invention of the application of nano-titanium dioxide photocatalytic materials in the sealed-off carbon dioxide laser tube. Background technique: [0002] In the prior art, a sealed carbon dioxide laser tube is generally composed of a discharge tube, a gas storage sleeve, a water cooling tube, an output mirror, a total reflection mirror and coaxial electrodes. Among them, the discharge tube, water-cooled tube and gas storage sleeve are made of glass or quartz materials, and the total reflection mirror is generally made of glass, quartz or silicon and other materials. After polishing, the surface is coated with gold, silver and other thin films by vacuum coating method. Coaxial electrode materials are generally made of gold, silver (silver-copper alloy), tantalum, platinum, nickel, titanium and other metals or ceramic materials such as stronti...
