Atomic bandpass filters are used in a variety of applications due to their narrow bandwidths and high transmission at specific frequencies. Predominantly, these filters are in the Faraday (Voigt) geometry, using an applied axial (transverse) magnetic...

Cascading light through two thermal vapour cells has been shown to improve the performance of atomic filters that aim to maximise peak transmission over a minimised bandpass window. In this paper, we explore the atomic physics responsible for the ope...

Laser spectroscopy of hot atomic vapours: from ’scope to theoretical fit (2022)
Journal Article
Pizzey, D., Briscoe, J. D., Logue, F. D., Ponciano-Ojeda, F. S., Wrathmall, S. A., & Hughes, I. G. (2022). Laser spectroscopy of hot atomic vapours: from ’scope to theoretical fit. New Journal of Physics, 24, https://doi.org/10.1088/1367-2630/ac9cfe

The spectroscopy of hot atomic vapours is a hot topic. Many of the work-horse techniques of contemporary atomic physics were first demonstrated in hot vapours. Alkali-metal atomic vapours are ideal media for quantum-optics experiments as they combine... Read More about Laser spectroscopy of hot atomic vapours: from ’scope to theoretical fit.

Better magneto-optical filters with cascaded vapor cells (2022)
Journal Article
Logue, F. D., Briscoe, J. D., Pizzey, D., Wrathmall, S. A., & Hughes, I. G. (2022). Better magneto-optical filters with cascaded vapor cells. Optics Letters, 47(12), 2975-2978. https://doi.org/10.1364/ol.459291

Single-cell magneto-optical Faraday filters find great utility and are realized with either ‘wing’ or ‘line center’ spectral profiles. We show that cascading a second cell with independent axial (Faraday) or transverse (Voigt) magnetic field leads to... Read More about Better magneto-optical filters with cascaded vapor cells.

Absorption spectroscopy and Stokes polarimetry in a 87Rb vapour in the Voigt geometry with a 1.5 T external magnetic field (2020)
Journal Article

Journal of Physics B: Atomic, Molecular and Optical Physics, 54(1), Article 015401. https://doi.org/10.1088/1361-6455/abc7ff

This paper provides details of a spectroscopic investigation of a thermal 87Rb atomic vapour. The experiment was conducted with an external magnetic field of 1.5 T in the Voigt geometry. Very good quantitative agreement between experimental data and...
