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 tuneable wavelength reference for chip-scale laser cooling
S. Dyer, K. Gallacher, U. Hawley +6
We demonstrate a tuneable, chip-scale wavelength reference to greatly reduce the complexity and volume of cold-atom sensors. A 1 mm optical path length micro-fabricated cell provid…
A grating-chip atomic fountain
Ben Lewis, Rachel Elvin, Aidan S. Arnold +2
Cold atom fountain clocks provide exceptional long term stability as they increase interrogation time at the expense of a larger size. We present a compact cold atom fountain using…
Micro-machined deep silicon atomic vapor cells
S. Dyer, P. F. Griffin, A. S. Arnold +4
Using a simple and cost-effective water jet process, silicon etch depth limitations are overcome to realize a mm deep atomic vapor cell. While the minimum silicon feature size…
A simple imaging solution for chip-scale laser cooling
A. Bregazzi, P. F. Griffin, A. S. Arnold +6
We demonstrate a simple stacked scheme that enables absorption imaging through a hole in the surface of a grating magneto-optical trap (GMOT) chip, placed immediately below a micro…
