Paper Abstract

We experimentally examined our proposed structure for realizing the control of resonant and lasing properties even in random structures, which was composed of size-mono-dispersive scatterers and intentionally introduced defect regions. In the experiments, by intentionally introducing polymer nanoparticles as point defects into a mono-dispersive zinc oxide nanoparticle film, we succeeded that lasing properties at the defect region were drastically modified, comparing with those of typical random lasers; suppression of the number of lasing modes, decrease in the thresholds, and limiting the lasing position at the defect. These results suggest the possibility that we can realize single-mode random lasers with well-controlled modal properties even in random structures.
