Optical pumping enhancement of a free-induction-decay magnetometer
Dominic Hunter, Marcin S. Mrozowski, Allan McWilliam +4
Spin preparation prior to a free-induction-decay (FID) measurement can be adversely affected by transverse bias fields, particularly in the geophysical field range. A strategy that…
Practical Doppler broadening thermometry
Nicola Agnew, Graham Machin, Erling Riis +1
We report initial research to develop a compact and practical primary thermometer based on Doppler broadening thermometry (DBT). The DBT sensor uses an intrinsic property of therma…
Optimal binary gratings for multi-wavelength magneto-optical traps
Oliver S. Burrow, Robert J. Fasano, Wesley Brand +6
Grating magneto-optical traps are an enabling quantum technology for portable metrological devices with ultracold atoms. However, beam diffraction efficiency and angle are affected…
A cold-atom Ramsey clock with a low volume physics package
Alan Bregazzi, Etienne Batori, Ben Lewis +4
We demonstrate a Ramsey-type microwave clock interrogating the 6.835~GHz ground-state transition in cold \textsuperscript{87}Rb atoms loaded from a grating magneto-optical trap (GM…
An additive-manufactured microwave cavity for a compact cold-atom clock
Etienne Batori, Alan Bregazzi, Ben Lewis +4
We present an additive-manufactured microwave cavity for a Ramsey-type, double resonance, compact cold-atom clock. Atoms can be laser cooled inside the cavity using a grating magne…
Real-time buffer gas pressure tuning in a micro-machined vapor cell
S. Dyer, A. McWilliam, D. Hunter +7
We demonstrate a controllable depletion of the nitrogen buffer gas pressure in a micro-machined cesium (Cs) vapor cell from the dynamic heating of an alkali dispenser pill. When th…
