    "abstract": "We propose a realistic scheme for measuring the micromaser linewidth by\nmonitoring the phase diffusion dynamics of the cavity field. Our strategy\nconsists in exciting an initial coherent state with the same photon number\ndistribution as the micromaser steady-state field, singling out a purely\ndiffusive process in the system dynamics. After the injection of a\ncounter-field, measurements of the population statistics of a probe atom allow\nus to derive the micromaser linewidth. Our proposal aims at solving a classic\nand relevant decoherence problem in cavity quantum electrodynamics, allowing to\nestablish experimentally the distinctive features appearing in the micromaser\nspectrum due to the discreteness of the electromagnetic field.",
