A roughly equal level of dead-time uncertainty and frequency-transfer uncertainty was chosen in order to give a total uncertainty (row 7) of 8.8×10-16. This is the first report of a primary frequency standard into TAI with a total uncertainty of less than 1×10-15. 2.

Cesium atomic frequency standard - Big Chemical Encyclopedia

Cesium atomic frequency standard Abstract. A suitable femtosecond (fs) laser system can provide a broad band comb of stable optical frequencies and thus can serve as an rf/optical coherent link. In this way we have performed a direct comparison of the IS — 2S transition in atomic hydrogen at 121 nm with a cesium fountain clock, built at the LPTF/Paris, to reach an accuracy of 1.9 x 10-14.
