We present an experimental study of energy transfer in a thermal vapor of atomic rubidium. We measure the fluorescence spectrum in the visible and near infra-red as a function of atomic density using confocal microscopy. At low density we observe energy transfer consistent with the well-known energy pooling process. In contrast, above a critical density we observe a dramatic enhancement of the fluorescence from high-lying states that is not to be expected from kinetic theory. We show that the…

Absolute Absorption and Dispersion in a Thermal Rb Vapour at High Densities and High Magnetic Fields.

This thesis presents a comparative study of the measured and calculated absolute absorption and dispersion properties of the Rb D lines through a dense thermal vapour in the absence and presence of

Resonant pulse propagation in dense atomic vapours

This thesis presents theoretical models and results of numerical simulations describing the propagation of optical pulses through dense, thermal atomic vapours. In particular we investigate the

Applications of the Faraday effect in hot atomic vapours

This thesis presents both a computational and experimental investigation into light propagation in hot alkali-metal vapours, with a particular focus on utilizing the Faraday effect for practical

Active narrowband filtering, line narrowing and gain using ladder electromagnetically induced transparency in an optically thick atomic vapour

Electromagnetically induced transparency (EIT) resonances using the 5S1/2 → 5P3/2 → 5D5/2 ladder-system in optically thick Rb atomic vapour are studied. We observe a strong line narrowing effect and

Rydberg atom ensembles under dephasing and dissipation: from single- to many-body dynamics

This thesis explores the effects of decoherence and dephasing on single- and many- body dynamics of spin-systems. A particular realisation of the spin systems that the work focuses on are highly
