The applications of diode lasers to frequency standards and optical frequency standards at CMS

In the last few years, CMS (Center for Measurement Standards in Taiwan) had devoted to the development of some of the recommended radiations of length standards. Most radiations at CMS were gas lasers. Recently, solid state lasers and semiconductor lasers have been highly improved in performance, thus they could be widely used in many applications in measurement standards. To fit the future needs, we have planned to build up our iodine stabilized diode pump Nd-YAG laser and begun to use diode lasers in the research on measurement standards.
