氦氖激光器是国内应用最广、产量最大的气体激光器。它亮度大、方向性好,在工业计量检测、矿山掘进定向、建筑准直定位、治疗疾病、全息照相等方面用途广泛。氦氖激光器在制造过程中玻璃壳体与反射镜片的封接是生产激光器关键技术之一。国内生产的氦氖激光管由于封接用材料不过关等 He-Ne laser is the most widely used, the largest output of gas lasers. Its brightness, directionality is good, in a wide range of applications in industrial measurement testing, mining heading, building alignment, treatment of disease, holography and so on. Helium-neon laser in the manufacturing process of the glass shell and the reflection of the lens is one of the key technologies in the production of lasers. Domestic production of helium-neon laser tube sealing material, but off and so on
