Lasing stipulated by multiple random light scattering

The lasing stipulated by random multiple scattering is described in accordance with our observation and analysis. Light scattering in laser cavity habitually was associated with losses. However the statement about scattering as the losses is true until the feedback is realized on size cavity L≫1 -photon transport mean free path. When L∼1 gets the diffusive energy transport for light is set up and instead of interference amplitude a scalar adding of intensity starts- they say about a random feedback in laser media. It was studied and compared the main touchstones of the lasing in random scattering media with the known features for classic laser. Are found the similarity with amplified spontaneous emission (ASE) in diffusive regime and new features of lasing in regime of a strong wave localization.
