Abstract
Enhancement of the diffusive albedo from a random amplifying medium is discussed. A pump-probe setup is used to study the amplification of the reflected probe pulse light outside the backscattering cone. Strong super-reflection is measured and its dependence on the disorder strength is studied. An optimal disorder strength is observed at high excitation energy wherein the super-reflection is maximal. The origins of this behavior are traced to the interplay between the out-coupling and amplification from a disordered amplifying medium with an inhomogeneous distribution of gain.
