濟南旭澤電子科技有限公司 Jinan kotewall ze electronic technology Co., LTD 激光管主要由硬質(zhì)玻璃、諧振腔、電極三部分組成。 　　1．激光管硬質(zhì)玻璃部分；本部件由GG17料燒制成放電管、水冷套、儲氣套和回氣管而組成。封離式CO2激光器通常為三層套管結(jié)構(gòu)。里面的是放電管，中間是水凈套，外一層是儲氣套，回氣管是用于連通放電管和儲氣管。 　　2．激光管諧振腔部分：本部件由全反鏡和輸出反射鏡組成。諧振腔的全反鏡一般以光學(xué)玻璃為基底，表面渡金膜，金膜反射鏡在10.6um附近的反射率達98%以上；諧振腔的輸出反射鏡一般采用能透射10.6um輻射的紅外線材料鍺(Ge)為基底,在上面渡上多層介質(zhì)膜而制成。 　　3．激光管電極部分：CO2激光器一般采用冷陰極，形狀為圓筒形，陰極材料選用對激光器的壽命有很大的影響，對陰極材料的基本要求是：濺射率低，氣體吸收率小， 　　激光管主要規(guī)格型號以激光功率做為重要依據(jù)。目前常見型號為：15W,25W,40W,60W,80W. 　　不同功率的激光管主要區(qū)分為長度不同。如60W激光管為1200mm或1250mm，80W長度一般為1600mm. 激光管主要用于Co2激光加工設(shè)備。如激光雕刻機，激光切割機，激光打標(biāo)機等。 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
