自一九六○年秋,He-Ne激光器问世以来,气体激光器有了很大的发展,我国在1964年亦制成了He-Ne激光器。目前正在迅速发展中,气体激光器激光器类型中较多的一类激光器,占据着几千条谱线,稳定性,单色性最好。 按工作物质的性质;气体激光器可分为原子气体激光器,离子气体激光器,分子气体激光器,受激准分子气体激光器以及其他气体激光器五种。 （一）原子气体激光器 它主要是有氦、氖、氩、氪或氙类惰性气体以及分金属原子作为工作物质的激光器件,迄今已到29种具有受激振荡的气体元素,共拥有450条发射其波长范围从2163微米到4100埃。
Since the advent of He-Ne lasers in the fall of 1960, gas lasers have greatly developed. In 1964, China also made He-Ne lasers. Currently, there is a rapid development in which more lasers of the type of gas laser lasers occupy thousands of lines with the best stability and monochromaticity. According to the nature of the working substance; gas lasers can be divided into five kinds of atomic gas lasers, ion gas lasers, molecular gas lasers, excimer gas lasers and other gas lasers. (A) Atomic gas laser It is mainly a helium, neon, argon, krypton or xenon type of inert gas and sub-atomic metal as a working substance of the laser device, so far has been to 29 kinds of excited oscillation gas elements, a total of 450 Its wavelength range is from 2163 microns to 4100 angstroms.
