Optical frequency ratio of a $^{171} Yb^{+}$ single-ion clock and a $^{87} Sr$ lattice clock

Sören Dörscher, Nils Huntemann, Roman Schwarz +6

We report direct measurements of the frequency ratio of the 642 THz $^{2} S_{1/2} (F = 0)$ -- $^{2} F_{7/2} (F = 3)$ electric octupole transition in $^{171} Yb^{+}$ and the 429 THz…

Long term measurement of the $^{87}$ Sr clock frequency at the limit of primary Cs clocks

R. Schwarz, S. Dörscher, A. Al-Masoudi +7

We report on a series of 42 measurements of the transition frequency of the 429~THz (5s $^{2}$ )~ $^{1}$ S $_{0}$ --(5s5p)~ $^{3}$ P $_{0}$ line in $^{87}$ Sr taken over three years from 2017 to 2019.…
