Journal Article

We measure the resonance line shape of atomic-vapor layers with nanoscale thickness confined between two sapphire windows. The measurement is performed by scanning a probe laser through resonance and collecting the scattered light. The line shape is...

Optimization of atomic Faraday filters in the presence of homogeneous line broadening (2015)
Journal Article

Journal of Physics B: Atomic, Molecular and Optical Physics, 48(18), Article 185001. https://doi.org/10.1088/0953-4075/48/18/185001

We show that homogeneous line broadening drastically affects the performance of atomic Faraday filters. We study the effects of cell length and find that the behaviour of 'line-centre' filters are quite different from 'wing-type' filters, where the e...

Electromagnetically induced absorption in a nondegenerate three-level ladder system (2015)
Journal Article

We investigate, theoretically and experimentally, the transmission of light through a thermal vapor of three-level ladder-type atoms, in the presence of two counterpropagating control fields. A simple theoretical model predicts the presence of electr... Read More about Electromagnetically induced absorption in a nondegenerate three-level ladder system.

Absolute absorption on the potassium D lines: theory and experiment (2015)
Journal Article

We present a detailed study of the absolute Doppler-broadened absorption of a probe beam scanned across the potassium D lines in a thermal vapour. Spectra using a weak probe were measured on the 4S $\to $ 4P transition and compared to the theoretical... Read More about Absolute absorption on the potassium D lines: theory and experiment.

Atomic Faraday filter with equivalent noise bandwidth less than 1  GHz (2015)
Journal Article

We demonstrate an atomic bandpass optical filter with an equivalent noise bandwidth less than 1 GHz using the D1 line in a cesium vapor. We use the ElecSus computer program to find optimal experimental parameters and find that, for important quantiti...

Hilbert transform: applications to atomic spectra (2015)
Journal Article

In many areas of physics, the Kramers-Kronig relations are used to extract information about the real part of the optical response of a medium from its imaginary counterpart. In this paper we discuss an alternative but mathematically equivalent appro... Read More about Hilbert transform: applications to atomic spectra.
