The effect of an external resonator on the emission of a GaAs microcavity with embedded quantum wells is investigated experimentally and theoretically. It was shown that the external resonator controls the process of the stimulated emission of the microcavity leading to the threshold‐like appearance of closely separated modes in a spectrum and to oscillations in the temporal dynamics of the emission. Investigation of the spatial coherence with a temporal resolution shows a complex phase dynamics related to the interplay between the lasing modes and reveals a strong spatial inhomogeneity of a phase within each mode.
