Two-photon Doppler-free spectroscopy of the $6 s^{2}^{1} S_{0} \to 6 s 23 s^{1} S_{0}$ Rydberg transition for quantum sensing in ytterbium

Benjamin D. Hunt, Kyle Beloy, Roger C. Brown +5

Here we report atomic structure calculations and experimental observations of the two-photon $6 s^{2}^{1} S_{0} \to 6 s 23 s^{1} S_{0}$ transition in Yb. The unique level structure of…

Atomic clock frequency ratios with fractional uncertainty $\leq 3.2 \times 1 0^{- 18}$

Alexander Aeppli, Willa J. Arthur-Dworschack, Kyle Beloy +24

We report high-precision frequency ratio measurements between optical atomic clocks based on $^{27}$ Al $^{+}$ , $^{171}$ Yb, and $^{87}$ Sr. With total fractional uncertainties at or bel…
