Abstract

Monte-Carlo simulation of random lasing under diffusive regime of light propagation in active random medium was carried out. Computing has been carried out for active media being suspension of dielectric particles in rhodamine 6G solution. Dependence of emitted photons density distribution in active media, their total quantity and spectrum on active medium length in a pump beam direction. Spatial distributions of pump radiation and amplification in a sample have been taken into account. It has been shown that quantity of emitted photons non-steadily depends on sample length and the maximal density of emitted photons is located at a depth near front (pump) sample side. Optimal active medium length is exists and maximizes total number of emitted photons and narrows spectrum of emission. Computing results are conformed to experiments.
