Transformation of vector modes by the Faraday effect in strong magnetic fields
Sphinx J. Svensson, Craig J. A. Millar, Danielle Pizzey +2
Large Faraday rotations can be generated by circular birefringence of atomic samples in an axial magnetic field in the vicinity of atomic resonance lines. The Faraday angle is a fu…
Experimental and theoretical characterisation of Stokes polarimetry of the potassium D1 line with neon buffer gas broadening
Sharaa A. Alqarni, Danielle Pizzey, Steven A. Wrathmall +1
This study presents a comprehensive experimental and theoretical characterisation of Stokes polarimetry in potassium (K) vapour on the D1 line. Measurements were performed in the w…
Visualizing strongly focused 3D light fields in an atomic vapor
Sphinx Svensson, Clare R. Higgins, Danielle Pizzey +2
Structured light, when strongly focused, generates highly confined vectorial electromagnetic field distributions which may feature a polarization component along the optical axis.…
Light propagation through an atomic vapor with non-orthogonal electric field modes
Jack D. Briscoe, Danielle Pizzey, Robert M. Potvliege +2
Alkali-metal atomic vapors are the foundation of an ever-growing range of applications, driven by a comprehensive understanding of their interaction with light. In particular, many…
The Role of Buffer Gas in Shaping the D1 Line Spectrum of Potassium Vapour
Sharaa A. Alqarni, Danielle Pizzey, Steven A Wrathmall +1
In this study, we investigate the effect of buffer gas and magnetic field on the spectral line shapes of the potassium D1 transition using sealed vapour cells filled with varying a…
Modelling spectra of hot alkali vapour in the saturation regime
Daniel R Häupl, Clare R Higgins, Danielle Pizzey +5
Laser spectroscopy of hot atomic vapours has been studied extensively. Theoretical models that predict the absolute value of the electric susceptibility are crucial for optimising…
Fine-structure changing collisions in Rb upon D2 excitation in the hyperfine Paschen-Back regime
Clare R. Higgins, Danielle Pizzey, Ifan G. Hughes
We investigate fine structure changing collisions in Rb vapour upon D2 excitation in a thermal vapour at 350 K; the atoms are placed in a 0.6 T axial magnetic field in order…
Indirect measurement of atomic magneto-optical rotation via Hilbert transform
Jack D Briscoe, Danielle Pizzey, Steven A Wrathmall +1
The Kramers-Kronig relations are a pivotal foundation of linear optics and atomic physics, embedding a physical connection between the real and imaginary components of any causal r…
A device for magnetic-field angle control in magneto-optical filters using a solenoid-permanent magnet pair
Sharaa A. Alqarni, Jack D. Briscoe, Clare R. Higgins +4
Atomic bandpass filters are used in a variety of applications due to their narrow bandwidths and high transmission at specific frequencies. Predominantly these filters in the Farad…
Exploiting non-orthogonal eigenmodes in a non-Hermitian optical system to realize sub-100 MHz magneto-optical filters
Fraser D. Logue, Jack. D. Briscoe, Danielle Pizzey +2
Non-Hermitian physics is responsible for many of the counter-intuitive effects observed in optics research opening up new possibilities in sensing, polarization control and measure…
Voigt transmission windows in optically thick atomic vapours: a method to create single-peaked line centre filters
Jack D Briscoe, Fraser D Logue, Danielle Pizzey +2
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…
Better magneto-optical filters with cascaded vapor cells in the Faraday-Faraday and Faraday-Voigt geometries
Fraser D. Logue, Jack D. Briscoe, Danielle Pizzey +2
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 ind…
Tuneable homogeneous kG magnetic field production using permanent magnets
