An ion trap design for a space-deployable strontium-ion optical clock
Alessio Spampinato, Jonathan Stacey, Sean Mulholland +5
Optical atomic clocks demonstrate a better stability and lower systematic uncertainty than the highest performance microwave atomic clocks. However, the best performing optical clo…
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…
Compact laser system for a laser-cooled ytterbium ion microwave frequency standard
S. Mulholland, H. A. Klein, G. P. Barwood +6
The development of a transportable microwave frequency standard based on the ground-state transition of at ~12.6 GHz requires a compact laser system for coo…
Laser-cooled ytterbium ion frequency standard
S. Mulholland, H. A. Klein, G. P. Barwood +6
We report on the development of a trapped-ion, microwave frequency standard based on the 12.6 GHz hyperfine transition in laser-cooled ytterbium-171 ions. The entire system fits in…
