Abstract

The competition on population inversion between two lasing modes in one-dimensional (1D) active random media is investigated by simultaneously solving Maxwell's equations and rate equations of electronic population. Results indicated that the increasing of concentration of the dye increase the spectral intensity of the dimer and the increase of the pump energy produces a major radiative and non-radiative energy transfers from monomers to dimers. The simulations of the new monomerdimer laser model agree very well with the experimental datas and promote the development of random lasing in the mixed dye media.
