    "abstract": "We propose a two-photon micromaser-based scheme for the generation of a\nnonclassical state from a mixed state. We conclude that a faster, as well as a\nhigher degree of field purity is achieved in comparison to one-photon\nprocesses. We investigate the statistical properties of the resulting field\nstates, for initial thermal and (phase-diffused) coherent states.\nQuasiprobabilities are employed to characterize the state of the generated\nfields.",
