摘要：

We present the first quantum microscopic study of a micromaser with many atoms in the cavity. Excited atoms are injected in clusters with average number N̄ up to 100. The stationary state of radiation is evaluated by means of a novel Green-function Monte Carlo technique. For N̄<Nex (Nex being the number of excited atoms entering the cavity in a photon lifetime) the system behaves similarly to the one-atom maser. At N̄Nex a transition occurs to a novel cluster behavior, where a fine structure of thresholds emerges. © 1995 The American Physical Society.
