Abstract
All the work presented in this thesis was conducted using caesium vapour, and so we start by presenting an overview of caesium atomic structure and atom-light interactions. We discuss gross, fine and hyperfine structure, with specific reference to caesium, and use the master equation formalism to describe a 2-level atom interacting with a resonant electromagnetic field. We outline a method to infer spontaneous fluorescence into separate spatial modes using a decay operator. The theory presented in this chapter forms a foundation for interpreting the experimental results presented in the rest of the thesis.
