Abstract

The elastic multiple light scattering (EMLS) at which a partial confinement of photons within the limits of area, where amplification exists, promotes development of a lasing with all tags of amplified stimulated emission (ASE). Because the spectral narrowing of the lasing with pumping power growing runs fluently without any catastrophe tags, possible for the case of arbitrary resonances (cavity modes, distributed feedback or Anderson localization modes), the lasing emission conserves the initial smooth spectral power distribution in spite of the strong spectral narrowing in the mass. Simple theoretical description of ASE stipulated EMLS in relation of band width evolution and scaled threshold conditions that is based upon the approximate determination of mean free path in EMLS media as l≈(Nσ_sct -α_gain)^-1 and Kubelka-Munk model are completed.
