The emission property of two-dimensional random laser under femtosecond laser pumping is theoretically investigated by using the time-dependent theory. The effects of peak intensity, duration and shape of a pumping pulse on temporal property of the random laser emission are discussed. Results show that the behavior of random lasing depends strongly on the pumping process, thereby one can control the random laser output waveshape through modifying the pumping parameters. The present work can provide more guidance for the controllability of random laser.
