Abstract
We report on coherent backscattering measurements from amplifying rand om media using optically pumped Ti:sapphire powders. The top of the ba ckscattering cone sharpens with increasing gain, reflecting a change i n the relative contributions to the intensity from paths of different lengths. A calculation based on diffusion theory is performed on coher ent backscattering from amplifying random media, which is in good agre ement with the data.
