摘要

A numerical analysis of the saturation effects of emitted light intensity in two-photon pumping random lasers is presented by adding the saturation item to modify the gain in the diffusive equation. Numerical results show that the emitted intensity reaches its saturation value in a short time interval with sufficient pumping. From the analysis of normalized emitted intensity and saturation intensity, one can obtain a method to control steady output intensity of two-photon pumping random lasing by adjusting some parameters of the random media.
