济南旭泽电子科技有限公司 Jinan kotewall ze electronic technology Co., LTD 激光管主要由硬质玻璃、谐振腔、电极三部分组成。 　　1．激光管硬质玻璃部分；本部件由GG17料烧制成放电管、水冷套、储气套和回气管而组成。封离式CO2激光器通常为三层套管结构。里面的是放电管，中间是水净套，外一层是储气套，回气管是用于连通放电管和储气管。 　　2．激光管谐振腔部分：本部件由全反镜和输出反射镜组成。谐振腔的全反镜一般以光学玻璃为基底，表面渡金膜，金膜反射镜在10.6um附近的反射率达98%以上；谐振腔的输出反射镜一般采用能透射10.6um辐射的红外线材料锗(Ge)为基底,在上面渡上多层介质膜而制成。 　　3．激光管电极部分：CO2激光器一般采用冷阴极，形状为圆筒形，阴极材料选用对激光器的寿命有很大的影响，对阴极材料的基本要求是：溅射率低，气体吸收率小， 　　激光管主要规格型号以激光功率做为重要依据。目前常见型号为：15W,25W,40W,60W,80W. 　　不同功率的激光管主要区分为长度不同。如60W激光管为1200mm或1250mm，80W长度一般为1600mm. 激光管主要用于Co2激光加工设备。如激光雕刻机，激光切割机，激光打标机等。 Laser tubes mainly by horniness glass, resonator and electrode of three parts. 1. Laser tube horniness glass parts; The parts are made of GG17 material fire becomes discharge tube, water-cooled sets, a gas storage sets and back of the trachea. Sealing from type CO2 laser is usually three layer casing structure. Most inside is discharge tube, the middle one is clean water, the outside layer of gas reservoir are set, back to the trachea is used for connecting tube and store the trachea. 2. Laser tube resonator part: the parts from the entire anti mirror and output mirrors composition. All the reverse resonator mirrors general with optical glass for basal, surface guandu gold membrane, gold membrane reflector in 10.6 um nearby reflectivity reaches 98%; The output of resonator mirrors can generally USES the infrared radiation transmission 10.6 um Ge (Ge) for material base, above crossing on multilayer dielectric film and manufactured. 3. Laser tube electrode parts: CO2 laser general use cold cathode, shapes for cylindrical, cathode material selection on the service life of laser tube had great effects on the basic requirements of cathode materials is: sputtering rate is low, the gas absorption rate is small, laser tubes mainly specifications with laser power as the most important basis. The most common type: 15W, 25W, 40 w, 60W, 80W. Different power laser tubes mainly divided into different lengths
