We generalize the concept of Husimi functions to active optical microresonators by introducing dynamical Husimi functions at the interfaces of dielectric laser cavity systems. To this end we solve the spatio-temporal laser cavity equations in the Schroedinger-Bloch model and deduce generalized, time-dependent Husimi functions. These functions give insight into the dynamics of the lasing modes in phase-space that conveniently complements the information derived from the time-dependence of the modes in configuration space. We apply these functions to characterize the near and far field optical properties of various two-dimensional microcavity systems.
