Optical coherence between atomic species at the second scale: improved clock comparisons via differential spectroscopy
May E. Kim, William F. McGrew, Nicholas V. Nardelli +9
Comparisons of high-accuracy optical atomic clocks \cite{Ludlow2015} are essential for precision tests of fundamental physics \cite{Safronova2018}, relativistic geodesy \cite{McGre…
High-performance, compact optical standard
Zachary L. Newman, Vincent Maurice, Connor Fredrick +6
We describe a high-performance, compact optical frequency standard based on a microfabricated Rb vapor cell and a low-noise, external cavity diode laser operating on the Rb two-pho…
Frequency Ratio Measurements with 18-digit Accuracy Using a Network of Optical Clocks
Boulder Atomic Clock Optical Network, Collaboration, : +35
Atomic clocks occupy a unique position in measurement science, exhibiting higher accuracy than any other measurement standard and underpinning six out of seven base units in the SI…
Ramsey-Bordé matter-wave interferometry for laser frequency stabilization at frequency instability and below
Judith Olson, Richard W. Fox, Tara M. Fortier +6
We demonstrate Ramsey-Bordé (RB) atom interferometry for high performance laser stabilization with fractional frequency instability for timescales between 10 a…
Demonstration of a time scale based on a stable optical carrier
William R. Milner, John M. Robinson, Colin J. Kennedy +13
We demonstrate a time scale based on a phase stable optical carrier that accumulates an estimated time error of ps over 34 days of operation. This all-optical time scale…
Measurements of Al and Mg magnetic constants for improved ion clock accuracy
S. M. Brewer, J. -S. Chen, K. Beloy +14
We have measured the quadratic Zeeman coefficient for the optical clock transition in Al, ~MHz/T, an…
