Optical Lattice Clocks toward 10−17 Uncertainty

Hidetoshi Katori

The concept and recent progress of optical lattice clocks are reviewed. With the clock uncertainty of 10−17 in perspective, we discuss new challenges in optical lattice clocks and possible applications of such highly accurate and stable atomic clocks.

particular 'magic' wavelengths. This Review covers the experimental realizations of such clocks, the optimal design of optical lattices and recent demonstrations of improved stability for large numbers of atoms. Possible impacts and future applications of optical lattice clocks are also discussed, such as testing the fundamental laws of physics and developing relativistic geodesy.

8half a century ago and have provided the definition of the second since 1967. The international atomic time (TAI) is currently kept by an ensemble of Cs clocks with a fractional uncertainty of Δν/ν0 ≈ 10 –15 , and some Cs fountain clocks 9,10 operate at even smaller uncertainties. Although Cs atomic clocks operate at the microwave transition of ν0 ≈ 9.2 GHz, using optical transition frequencies of several hundred terahertz should improve the fractional uncertainty Δν/ν0 by 4–5 orders of magnitude, as most measurement uncertainties Δν are independent of ν0 (except the Doppler shift Δ νD = (v/c)ν0, where v is the atomic velocity and c is the speed of light).

Optical lattice clocks

P. Lemonde

The idea of using cold atoms confined in an optical lattice for an optical clock was proposed in 2001. Since then, this idea became an experimental reality. We review here the contribution of LNE-SYRTE to these developments.
