Improving the Q factor of an optical atomic clock using quantum non-demolition measurement
William Bowden, Alvise Vianello, Ian R Hill +2
Quantum non-demolition (QND) measurement is a remarkable tool for the manipulation of quantum systems. It allows specific information to be extracted while still preserving fragile…
A strontium optical lattice clock with uncertainty and measurement of its absolute frequency
Richard Hobson, William Bowden, Alissa Silva +5
We present a measurement of the absolute frequency of the 5s S to 5s5p P transition in Sr, which is a secondary representation of the SI second. We descr…
A mid-infrared magneto-optical trap of metastable strontium for an optical lattice clock
Richard Hobson, William Bowden, Alvise Vianello +2
We report on the realization of a magneto-optical trap (MOT) for metastable strontium operating on the 2.92 m transition between the energy levels and $5s4…
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…
