Abstract
-
There are few systems in physics which can be investigated under clean experimental conditions and at the same time can be studied starting from first principles, using exact theoretical methods. The single-atom maser or micromaser is one of these remarkable systems, it allows us a detailed study of the atom-field interaction. The situation realized in a micromaser is very close to the ideal case of a single two-level atom interacting with a single quantized mode of a superconducting cavity. Considerable amount of work, both theoretical and experimental, has been devoted to the study of this system. However, it remains to be established how the system behaves under coherent pumping. In this work our goal is to provide a comprehensive study of the coherently pumped micromaser. We derive the master equation governing the time evolution of the field inside the coherently pumped micromaser. We then solve the resulting equation of motion, first by using the semiclassical approximation which we extend to handle the case of the coherently pumped micromaser. Then we develop a new analytical method to obtain the full quantum mechanical solution. We also generalize the trapping states of the micromaser for the case of the coherently pumped micromaser and provide a clear physical picture of the full quantum mechanical solution. Finally we derive the phase density function describing the result of an optimal measurement of the phase of the coherently pumped micromaser's field. With the help of this density function we study the phase properties of the steady state field and determine bistable and multistable regions of operation.
