摘要: | 我們利用氧化鋅轉印巴黎翠鳳蝶翅膀鱗片上的半規則結構,發現隨機雷射(random laser)產生可控制波段的光學特色。很有趣地,從氧化鋅轉印樣品上發現的隨機雷射現象展現許多特殊的光學特色,這些特色無法在一般常見奈米結構的氧化鋅上發現。此種新發現隨機雷射現象不只具有超窄半高寬,而且可利用鳳蝶翅膀鱗片上的半規則結構來控制雷射波段。我們可以利用隨機雷射以及由於半規則結構產生的Fabry-Perot共振現象,解釋此種奇妙的雷射性質。此種性質透露出生物引發性研究朝向完全控制隨機雷射波段具有高度的潛力。這項研究成果開創出實現進階隨機雷射的新方法,以及更進一步產生學術研究的興趣和實際應用。 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. |
