Ramsey-Bordé matter-wave interferometry for laser frequency stabilization at $1 0^{- 16}$ 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 $< 2 \times 1 0^{- 16}$ 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 $48 \pm 94$ ps over 34 days of operation. This all-optical time scale…

Measurements of $^{27}$ Al $^{+}$ and $^{25}$ 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 $^{1} S_{0} \leftrightarrow^{3} P_{0}$ optical clock transition in $^{27}$ Al $^{+}$ , $C_{2} = - 71.944 (24)$ ~MHz/T $^{2}$ , an…
