Atomic fountains and optical clocks at SYRTE: status and perspectives
M. Abgrall, B. Chupin, L. De Sarlo +9
In this article, we report on the work done with the LNE-SYRTE atomic clock ensemble during the last 10 years. We cover progress made in atomic fountains and in their application t…
Absolute frequency measurement of the 40Ca+ S1/2 - D5/2 clock transition
M. Chwalla, J. Benhelm, K. Kim +12
We report on the first absolute transition frequency measurement at the 10^{-15} level with a single, laser-cooled 40Ca+ ion in a linear Paul trap. For this measurement, a frequenc…
An Optical Lattice Clock with Spin-polarized 87Sr Atoms
Xavier Baillard, Mathilde Fouché, Rodolphe Le Targat +14
We present a new evaluation of an 87Sr optical lattice clock using spin polarized atoms. The frequency of the 1S0-3P0 clock transition is found to be 429 228 004 229 873.6 Hz with…
Accuracy Evaluation of an Optical Lattice Clock with Bosonic Atoms
Xavier Baillard, Mathilde Fouché, Rodolphe Le Targat +6
We report the first accuracy evaluation of an optical lattice clock based on the 1S0 - 3P0 transition of an alkaline earth boson, namely 88Sr atoms. This transition has been enable…
An accurate optical lattice clock with 87Sr atoms
Rodolphe Le Targat, Xavier Baillard, Mathilde Fouché +4
We report a frequency measurement of the 1S0-3P0 transition of 87Sr atoms in an optical lattice clock. The frequency is determined to be 429 228 004 229 879 (5) Hz with a fractiona…
Accurate spectroscopy of Sr atoms
Irene Courtillot, Audrey Quessada-Vial, Anders Brusch +3
We report the frequency measurement with an accuracy in the 100 kHz range of several optical transitions of atomic Sr : at 689 nm, at 688 nm and $^3P_…
