87 Sr 1D Optical Lattice Clock With a 124 K Silicon Cavity: Full Systematic Evaluation and Record Precision
Abstract
We report on the full systematic evaluation of the JILA Sr1 optical lattice clock using a laser stabilized to a 124 K silicon cavity. This evaluation resulted in a factor of 10 improvement over our previous evaluation of JILA Sr1 for the systematic uncertainty. After the systematic evaluation of the JILA Sr2 clock at 2.1 ×10-18, it is now operating in a 3D lattice configuration. We perform an extensive comparison between JILA Sr1 and Sr2 clocks and determine independent clock stability of 4.8 ×10-17 at 1 s. With synchronous clock operation we achieve stability of 3.5 ×10-17 at 1 s and a precision of 6 ×10-19 in 1 hour of measurement. The state-of-the-art precision and accuracy of this clock enables measurements for wide-ranging applications, from searches for dark matter to relativistic geodesy.
