碩士 === 國立臺灣大學 === 物理研究所 === 103 === Mode-controllable random laser (RL) action has been demonstrated in ZnO replicas with quasi-periodic structures (QPSs) derived from Papilio paris butterfly wing scales. Interestingly, the random laser action of ZnO replicas exhibits several unique features that can not be found in common ZnO nanostructures. The newly discovered RL not only shows ultra-narrow FWHM with the linewidth less than 0.8 nm, but also possesses controllable modes selected by the QPSs of butterfly wing scales. The intriguing lasing characteristics can be well interpreted by the coupling between random laser action and Fabry-Perot resonance due to QPSs, which reveals the possibility of a highly bioinspired potential towards control of random laser modes. We believe that our approach, based on an efficient calcination method with low cost, may pave a new route to realize advanced random lasers, and further generate both academic interest and practical application.
