177. 孔雀羽毛激光之谜

from 知为谁 · host 知为谁

该新闻来源报道了一项研究发现,孔雀羽毛经过多次染色后能够发出激光束。与蝴蝶翅膀一样,孔雀羽毛的鲜艳虹彩并非来自色素,而是源于其独特的纳米结构,这些结构被称为光子晶体。研究人员通过将染料溶液滴到羽毛上并使其干燥,然后用光脉冲泵浦样本,观察到了激光发射。这项研究不仅展示了动物界中首次发现的生物激光腔,还提出利用孔雀羽毛的自然结构来设计新型生物兼容激光器的可能性,有望应用于人体传感、成像和治疗领域。内容来源:https://arstechnica.com/science/2025/07/scientists-use-peacock-feathers-to-make-frickin-laser-beams/
