Electromagnetically induced transparency in a V-system with Rb vapor in the hyperfine Paschen-Back regime
Clare R Higgins, Ifan G Hughes
We observe EIT in a V-system in a thermal rubidium-87 vapour in the hyperfine Paschen-Back regime, realised with a 0.6 T axial magnetic field. In this regime energy levels are no l…
The Raspberry Pi Auto-aligner: Machine Learning for Automated Alignment of Laser Beams
Renju S. Mathew, Roshan O'Donnell, Danielle Pizzey +1
We present a novel solution to automated beam alignment optimization. This device is based on a Raspberry Pi computer, stepper motors, commercial optomechanics and electronic devic…
Absorption spectroscopy and Stokes polarimetry in a Rb vapour in the Voigt geometry with a 1.5 T external magnetic field
Francisco S. Ponciano-Ojeda, Fraser D. Logue, Ifan G. Hughes
We present a detailed spectroscopic investigation of a thermal Rb atomic vapour in a magnetic field of 1.5~T in the Voigt geometry. We fit experimental spectra for all Stoke…
Atomic line versus lens cavity filters: A comparison of their merits
Clare R. Higgins, Danielle Pizzey, Renju S. Mathew +1
We present a comparison between lens cavity filters and atomic line filters, discussing their relative merits for applications in quantum optics. We describe the design, characteri…
Measuring the Faraday effect in olive oil using permanent magnets and Malus' law
Daniel L. Carr, Nicholas L. R. Spong, Ifan G. Hughes +1
We present a simple permanent magnet set-up that can be used to measure the Faraday effect in gases, liquids and solids. By fitting the transmission curve as a function of polarize…
Lattice-depth measurement using continuous grating atom diffraction
Benjamin T. Beswick, Ifan G. Hughes, Simon A. Gardiner
We propose a new approach to characterizing the depths of optical lattices, in which an atomic gas is given a finite initial momentum, which leads to high amplitude oscillations in…
