Web1 okt. 2024 · An absolute frequency measurement on the hyperfine components of the 5S 1/2 – 5D 3/2 two-photon transition in rubidium using an optical frequency comb is performed. In order to do so, a double optical frequency standard near 1556 nm and 778 nm is developed, which is based on the 5S 1/2 – 5D 3/2 two-photon transition in rubidium.

Web16 sep. 2024 · As has been mentioned, the parallel-mode transitions are enhanced in the case of large hyperfine interactions and small magnetic fields (low microwave frequencies). In the majority of cases, the hyperfine interactions are relatively small. Therefore, in these cases, the parallel-mode transitions can be hardly observed at X-band. Webour initial work is to accurately determine the 201Hg+ clock transition frequency (! 2 S 12 F =1,m F 0 to ! 2 12 F=2,m F), which up until now has only been known to 3 digits [8]. It is also possible to use accurate knowledge of the 201Hg+ hyperfine clock transition frequency together with that of 199Hg+ (already known) as a sensitive probe of ...
