Reconstructing the Wigner-Function of the Micromaser Field — •Pavel Lougovski¹, Enrique Solano¹, Z.M. Zhang¹, Herbert Walther¹, Holger Mack², and Wolfgang P. Schleich² — ¹Max-Planck-Institut für Quantenoptik, 85748 Garching — ²Abteilung für Quantenphysik, Universität Ulm, 89069 Ulm

We propose two methods to reconstruct directly the Wigner function of the micromaser field. For both methods the field is probed by measuring the atomic population of the Rydberg atoms in the maser levels after they left the cavity. By applying a Fresnel transformation to the measured data one can reconstruct directly the Wigner function. The second reconstruction scheme is based on an inversion of a system of linear equations.
