Guidelines for developing optical clocks with fractional frequency uncertainty
Moustafa Abdel-Hafiz, Piotr Ablewski, Ali Al-Masoudi +42
There has been tremendous progress in the performance of optical frequency standards since the first proposals to carry out precision spectroscopy on trapped, single ions in the 19…
Doppler-free spectroscopy of the 1S0-3P0 optical clock transition in laser-cooled fermionic isotopes of neutral mercury
M. Petersen, R. Chicireanu, S. T. Dawkins +5
We have performed for the first time direct laser spectroscopy of the 1S0-3P0 optical clock transition at 265.6 nm in fermionic isotopes of neutral mercury laser-cooled in a magnet…
Sr lattice clock at 1x10^{-16} fractional uncertainty by remote optical evaluation with a Ca clock
A. D. Ludlow, T. Zelevinsky, G. K. Campbell +16
Optical atomic clocks promise timekeeping at the highest precision and accuracy, owing to their high operating frequencies. Rigorous evaluations of these clocks require direct comp…
RF-induced evaporative cooling and BEC in a high magnetic field
P. Bouyer, V. Boyer, S. G. Murdoch +4
We present the design of our iron-core electromagnet for BEC, and how to solve the specific experimental problems raised by this technique. After presenting the experimental set-up…
