The one-atom maser or micromaser is a quantum optics system that allows the observation of single two-level atoms interacting with a single-mode field. The microscopic nature of the micromaser system and the absence of significant amounts of stochasticity and noise, allows for the observation of behavior that is drastically different from that of macroscopic masers. This dissertation describes theoretical studies of the micromaser system and extensions of the previous micromaser theory to improve its agreement with experimental observations.

This chapter discusses the novel aspects of cavity QED that are not only relevant to traditional quantum optics (lasers and masers, coherence theory, non-classical fields, etc.), but simultaneously make contact with nonlinear dynamics and chaos. A micromaser consisting of a single-mode cavity in which two-level atoms are injected at such a low rate that at most one atom at a time is present inside the cavity. In recent work, a complete quantum theory of the micromaser, including resonator losses, is presented. A detailed study of the dynamics of the quantum-mechanical micromaser is called for, and it will hopefully contribute to a better understanding of quantum chaos in dissipative quantum mechanical systems. A semi-classical version of the micromaser is generally chaotic and exhibits a number of coexisting basins of attraction. The micromaser is a truly quantum-mechanical system which is within reach of experimental investigations.
