| Description: | We report the first accuracy evaluation of an optical lattice clock based on the 1 S0 → 3 P0 transition of an alkaline earth boson, namely 88 Sr atoms. This transition has been enabled using a static coupling magnetic field. The clock frequency is determined to be 429 228 066 418 009(32) Hz. The isotopic shift between 87 Sr and 88 Sr is 62 188 135Hz with fractional uncertainty 5 ×10 −7. We discuss the conditions necessary to reach a clock accuracy of 10 −17 or less using this scheme. c ○ 2008 Optical Society of America OCIS codes: 020.3260, 020.6580, 020.7490, 120.3940. The recent advent of optical lattice clocks has opened a very promising avenue for the future of atomic frequency standards. 1–4 Like single ion clocks 5–8 they allow to efficiently cancel motional effects thanks to the lattice confinement. 9 In addition, they can operate with a large number of atoms and their expected ultimate performance is a relative frequency noise well below 10 −15 τ −1/2 (with τ the averaging time in seconds) combined with a control of systematic effects in the 10 −18 |
