A simplified four-level model which describes the qualitative features of one-atom laser in a regime of strong coupling was compared. It was found that decreasing the cavity length caused the model system to move from a regime of weak coupling, where the semiclassical laser theory applies, into a regime of strong coupling, where quantum deviations become important. The four-state model predicted many of the observed features of the experimental system, including the qualitative shape of the intracavity photon number versus pumping intensity curve and photon antibunching. A full multilevel model which correctly described optical pumping and Larmor precession effects within the Zeeman substructure.
