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…
Frequency stability and phase noise measurements of a 5,860 km-long intercontinental seafloor optical fibre cable
Giuseppe Marra, Paul Gaynor, Mattia Cantono +8
Optical clock comparison via optical fibre links has been achieved over continental scales, but has not yet been demonstrated intercontinentally. The transfer of ultra-stable optic…
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…
