The spectral property of dual-color random laser is investigated by simultaneously solving Maxwell鈥檚 equations and rate equations of electronic population in which the pumping rate is described by a time function with duration of hundreds of femtoseconds. Results show that the delay time and peak intensity of the emitted light depends strongly on the pumping process. An effective optimization method is proposed to exercise control over the dual-color laser emission from the dye solution with scattering nano-particles. It is demonstrated numerically that the controllable single mode operation of a dual-color random laser by choosing the proper pump profile and pumping region. The present work enriches the knowledge about random lasers and offers more guidance for relevant experiments.
