We propose a two-photon micromaser-based scheme for the generation of a non-classical state from a mixed state. We conclude that a faster, as well as a higher degree of field purity, is achieved in comparison to one-photon processes. We investigate the statistical properties of the resulting field states, for initial thermal and (phase-diffused) coherent states. Quasiprobabilities are employed to characterize the state of the generated fields
