We have experimentally found that in a random laser based on Nd0.5La0.5Al3(BO3)(4) scattering ceramic, the threshold pumping density decreases and the output slope efficiency increases with the increase of the diameter of the pumped spot. The experimental behavior is explained in terms of random photon's walk in an amplifying medium. (C) 2002 Elsevier Science B.V. All rights reserved.
