Cavity-enhanced non-destructive detection of atoms for an optical lattice clock
Richard Hobson, William Bowden, Alvise Vianello +2
We demonstrate a new method of cavity-enhanced non-destructive detection of atoms for a strontium optical lattice clock. The detection scheme is shown to be linear in atom number u…
A low-noise resonant input transimpedance amplified photodetector
William Bowden, Alvise Vianello, Richard Hobson
We present the design and characterisation of a low-noise, resonant input transimpedance amplified photodetector. The device operates at a resonance frequency of $90 \,\textrm{MHz}…
A pyramid MOT with integrated optical cavities as a cold atom platform for an optical lattice clock
William Bowden, Richard Hobson, Ian R. Hill +6
We realize a two-stage, hexagonal pyramid magneto-optical trap (MOT) with strontium, and demonstrate loading of cold atoms into cavity-enhanced 1D and 2D optical lattice traps, all…
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…
