Abstract
In this paper we present calculations on light diffusion with amplific ation that can explain previous experiments on the spontaneous emissio n from such a medium. Also we discuss the experimental considerations on realizing a medium that both multiply scatters and amplifies light. In an amplifying random medium different processes can occur. We argu e that one can distinguish three regimes depending on the amount of sc attering, and discuss these regimes in the context of random laser act ion.
