A random laser is a system formed by a random assembly of elastic scatters dispersed into an optical gain medium. We consider the case where the scattering is resonant. Our system, a photonic glass, can sustain scattering resonances over the gain frequency window, since it is formed by equal shape and equal size particles (monodisperse spheres) of relatively high refractive index contrast that are randomly assembled. The unique resonant scattering of this material allows controlling the laser emission via the diameter of the particles and their refractive index. Our system is therefore a random laser with a-priori designed lasing peak within the gain curve.
