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 $^{171} Y b^{+}$ 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…

Measurement of differential polarizabilities at a mid-infrared wavelength in $^{171} Yb^{+}$

C F A Baynham, E A Curtis, R M Godun +10

An atom exposed to an electric field will experience Stark shifts of its internal energy levels, proportional to their polarizabilities. In optical frequency metrology, the Stark s…
