Abstract

We have studied numerically the optimal range of the transport mean free path lt and the absorption length (at the pumping wavelength) la , which minimize the threshold and maximize the slope efficiency of a random laser with non-resonant feedback. The results of the calculations are in a good agreement with the experimental results obtained in the GaAs/Al2O3 random laser.
