We solve a realistic model for the micromaser using the IVlonte Carlo wave-function method.1 A beam of excited two-level atoms, with a given velocity distribution, crosses a resonant microwave cavity, at temperature T, containing an arbitrary field profile. Up to two atoms are considered to interact with the cavity mode at a, given time, the actual number of atoms present in the cavity being given by random choice, according to the pumping statistics. Whenever two atoms are inside the cavity, a two-atom Hamiltonian is used to calculate the evolution. Dissipation, as well as atomic decay and atomic detection, are taken into account through quantum jumps. Both single realizations and average values are calculated for the number of photons and the atomic population, thus allowing the simulation of a typical time-dependent experiment. In particular, the leaking of trapping states2 due to collective effects3 is observed under realistic conditions.
