We discuss a scheme to relate the phase diffusion dynamics of the micromaser field to the measured atomic population statistics. This can allow us to measure the Iinewidth of the micromaser spectrum and to solve a relevant decoherence problem in cavity quantum electrodynamics. The main steps are (i) a suitable preparation of the cavity field state to generate coherences, (ii) the transfer of information on the dynamics of field coherences to probe atoms by the action of an external resonant coherent field and (iii) the derivation of the phase diffusion rate, hence the micromaser Iinewidth, from the measured population statistics of the probe atoms. The method can be applied even in the presence of trapping states, where peculiar Iinewidth oscillations are expected for increasing pump rate, due to the quantum nature of the micromaser field.
