Resumo
We show that polydispersed powders can have much higher random laser output
power and efficiency than monodispersed powders. A more than 50% slope efficiency is
achieved by using highly doped Nd:YVO4 powders composed of average grains size of 50 μm
and 10% volume fraction of grains below 1 μm. We demonstrate that the smaller particles,
trapped between large particles, serve as gain centers whereas the large particles control the
light diffusion into the sample. A detailed light diffusion analysis of the samples explains the
observed differences.
