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 …

We present a computer program and underlying model to calculate the electric susceptibility
of a gas, which is essential to predict its absorptive and dispersive properties. Our program …

A light, compact optical isolator using an atomic vapor in the hyperfine Paschen–Back
regime is presented. Absolute transmission spectra for experiment and theory through an …

Narrow-band optical filtering is required in many spectroscopy applications to suppress
unwanted background light. One example is quantum communication where the fidelity is …

We present an experimental measurement of the refractive index of high density Rb vapor in
a gaseous atomic nanolayer. We use heterodyne interferometry to measure the relative …

We investigate experimentally and theoretically the Faraday effect in an atomic medium in
the hyperfine Paschen–Back regime, where the Zeeman interaction is larger than the …

We present a major update to ElecSus, a computer program and underlying model to
calculate the electric susceptibility of an alkali-metal atomic vapour. Knowledge of the …

Here we report on measurements of the absolute absorption and dispersion properties of an
isotopically pure 87 Rb vapour for magnetic fields up to and including 0.6 T. We discuss the …

We present an experimental study of seeded four-wave mixing (4WM) using a diamond
excitation scheme (with states from the 5 S 1/2, 5 P 1/2, 5 P 3/2 and 5 D 3/2 terms) in a …

We present experimental observations of atom-light interactions within tens of nanometers
(down to 11 nm) of a sapphire surface. Using photon counting we detect the fluorescence …
