We present a theory for light propagation and light intensity transport in thin random dielectric media with optical gain. The diffusing light intensity is coupled to the semiclassical laser rate equations. This coupled system of nonlinear equations is numerically solved for the stationary laser states. Our calculations predict two different types of random laser modes in effectively two‐dimensional systems. Surface modes which exhibit a large size and extend over the entire sample width, and also bulk modes with comparably small lasing areas.
