SR OPTICAL CLOCK WITH HIGH STABILITY AND ACCURACY

Andrew D. Ludlow, Sebastian Blatt, M. BOYD +12 more

We report on our recent evaluations of stability and accuracy of the JILA Sr optical lattice clock. We discuss precision tools for the lattice clock, including a stabilized clock laser with sub-Hz linewidth, fs-comb based technology allowing accurate clock comparison in both the microwave and optical domains, and clock transfer over optical fiber in an urban environment. High resolution spectroscopy (Q > 2 × 10^14) of lattice-confined, spin-polarized strontium atoms is used for both a high-performance optical clock and atomic structure measurement. Using a Ca optical standard for comparison, the overall systematic uncertainty of the Sr clock is reduced to < 2 × 10^−16We report on our recent evaluations of stability and accuracy of the JILA Sr optical lattice clock.
