Abstract

Recent results from the JILA ⁸⁷Sr optical lattice clock are presented. Using the tight confinement of an optical lattice in combination wit a sub-Hz linewidth diode laser we have achieved a pulse-length limited linewidth of 1.8 Hz for the ¹S₀- ³P₀ clock transition. This corresponds to a quality factor of Q ≈ 2.4 x 10¹⁴, and is a record for coherent spectroscopy. With the addition of a small magnetic bias field, the high line Q of the clock transition has also allowed us to resolve the nuclear-spin sublevels, and make a precision measurement of the differential Landé g-factor between the ¹S₀ and ³P₀. We present the current accuracy and stability of the lattice clock, and in addition, we report on our development of precision tools for the lattice clock, including a stabilized clock laser, fs-comb based technology allowing accurate clock comparison in both the microwave and optical domains, and clock transfer over an optical fiber in an urban environment.
