Differential clock comparisons with a multiplexed optical lattice clock
Nature, 2022Rapid progress in optical atomic clock performance has advanced the frontiers of timekeeping, metrology and quantum science1-3. Despite considerable efforts, the instabilities of most optical clocks remain limited by the local oscillator rather than the atoms themselves4,5.

We report on the precision spectroscopy of the 5s/sup 2/ /sup 1/S/sub o/(F=9/2)-5s5p /sup 3/P/sub o/(F=9/2) clock transition of /sup 87/Sr atoms trapped in a one-dimensional optical lattice and discuss its prospects as a future optical clock.

Nature, 2005
The precision measurement of time and frequency is a prerequisite not only for fundamental science but also for technologies that support broadband communication networks and navigation with global positioning systems (GPS). The SI second is currently realized by the microwave transition of Cs atoms with a fractional uncertainty of 10(-15) (ref.

A new breed of atomic clock—the “ticking” of which comes from transitions in millions of cooled atoms, trapped in optical standing waves created by tightly focused lasers—is pushing scientific timekeeping to previously unknown frontiers of precision.

The European Physical Journal Special Topics, 2009
The Idea of using cold atoms confined in an optical lattice for an optical clock was proposed in 2001 [1]. Since then, this idea became an experimental reality. We review here the contribution of LNE-SYRTE to these developments.

MAPAN, 2012
Latest progress in optical atomic clocks is so rapid that serious discussions toward the redefinition of the second is initiated. Besides single ion clocks developed since early 1980s, optical lattice clocks just invented a decade ago are one of strong candidates as a method to realize the revised definition.

Prospects for Optical Clocks with a Blue-Detuned Lattice
Physical Review Letters, 2009We investigated the properties of optical lattice clocks operated with a repulsive light-shift potential. The magic wavelength, where light-shift perturbation for the clock transition cancels, was experimentally determined to be 389.889(9) nm for 87Sr. The hyperpolarizability effects on the clock transition were investigated theoretically. With minimal

Contributing to TAI with Sr optical lattice clocks
2017 Joint Conference of the European Frequency and Time Forum and IEEE International Frequency Control Symposium (EFTF/IFC), 2017In this paper, we present recent experiments conducted with two 87Sr optical lattice clocks operated at LNE-SYRTE. We report on the first calibrations of TAI with optical clocks, a necessary step towards the redefinition of the SI second. Additionally, we report on the experimental realization of a cavity-assisted non-destructive detection whose ...
