title: Understanding bichromatic emission from scattering gain media.
abstract: Intense optical pumping of solutions of high-gain laser dyes and TiO(2) nanoscatterers in methanol is found to result in narrow-linewidth bichromatic emission. Experimental studies of the long-wavelength emission peak show that weak pumping of the scattering gain medium by the primary lasing emission results in a random system that lases at longer wavelengths. Measurements with other dyes show that the bichromatic emission effect is very general.
