On the phase structure of the micromaser system [PDF]

open access: yesOptics Communications, 2000
We investigate, in an exact manner, the phase structure of the micromaser system in terms of the physical parameters at hand like the atom cavity transit time, the atom-photon frequency detuning, the number of thermal photons and the probability for a pump atom to be in its excited state. Phase diagrams are mapped out for various values of the physical
