全内腔绿光He-Ne激光器

采用Needle法，对全内腔绿光He-Ne激光器膜系进行设计，并给出了所设计膜系的光谱性能。利用离子溅射镀膜技术镀制了所设计的膜片并且给出了测量结果。制备了多种规格的全内腔绿光He-Ne激光器并且讨论了相关工艺。其中腔长420mm的全内腔绿光He-Ne激光器的典型输出光功率为3mW（单模），腔长360mm的典型输出光功率为2mW（单模），腔长240mm的典型输出光功率为1mW（单模），腔长100mm的小短管子也能有0．1mw的出光功率。

Green He-Ne Laser with Internal Cavity

By making use of the needle method,the coating design of green He-Ne laser with internal cavity and the spectrum performance of the designed coating are introduced.The newly designed films of green HeNe laser have been coated by making use of ion beam sputtering deposition,and the measured results have been given out.Many types of green He-Ne laser with internal cavity have been fabricated and the related techniques have been discussed.In these green He-Ne lasers,the lasers with cavity length of 420 mm have typical output power of(3 mW)(single mode),the lasers of 360 mm have typical output power of 2 mW(single mode),the lasers of 240 mm have typical output power of 1 mW(single mode),and the small and short lasers with cavity length of 100 mm have also typical output power of 0.1 mW.
