A compacted random laser with a triple optical cavity is designed by directly coupling the compound between three cavities: the fundamental, ring, and external cavities. The laser action in this counterintuitive cavity is enabled by feedback from strong reflections on the inner and external surfaces, as well as scattering centers silver nanowires. This unique property of the triple optical cavity results in a lower laser threshold and enhanced emission spectra. These results provide up new possibilities for designing devices integrated and miniature technology.
