氦氖激光器中采用消气剂是一种克服因放气而缩短激光器寿命的行之有效的简单方法,装入消气剂应该在清洗完毕胶合腔片之前进行。首先用0.15毫米厚的镍片弯制成直径比毛细管外径略小的消气剂卡环,然后将消气剂与卡环的镍制连杆点焊于开口处,在连杆的另一端点焊上由两段小镍杆和两片舟状钡消气剂组成的框架,将组合的消气剂从贴片管口轻放入管内,并利用卡环的弹力紧固在毛细管的端头上。这种装配结构经 The use of getters in HeNe lasers is an effective and simple way to overcome the shortening of the life of the laser due to outgassing. The getter should be loaded before the adhesive cavity is cleaned. First 0.15mm thick nickel sheet bent to make the diameter slightly smaller than the diameter of the capillary getter ring, and then the getter and snap ring Nickel connecting rod in the opening at the other end of the connecting rod spot welding On the two sections of small nickel rod and two barium-based barium getter composition of the frame, the combination of the getter from the chip nozzle into the light tube, and the use of elastic snap ring cap on the capillary.
