Strontium Optical Lattice Clock at JILA

Results from the JILA optical lattice clock are presented. We report on our development of 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 times 1014) of lattice confined strontium atoms is used for both a high-performance optical clock and atomic structure measurements. The current accuracy and stability of the lattice clock are also discussed.
