Owing to the low-loss and high refractive index variations derived from the basic building block of bone structure, we, for the first time to our knowledge, demonstrate coherent random lasing action originated from the bone structure infiltrated with laser dye, revealing that bone tissue is an ideal biological material for random lasing. Our numerical simulation shows that random lasers are extremely sensitive to subtle structural changes even at nanoscales and can potentially be an excellent tool for probing nanoscale structural alterations in real time as a novel spectroscopic modality.
由于源自骨结构基本构建块的低损耗和高折射率变化，我们首次从我们所知的角度展示了源自激光染料渗透的骨结构的相干随机激光作用，揭示了骨组织是用于随机激光的理想生物材料。我们的数值模拟表明，随机激光对即使在纳米尺度下的细微结构变化也极其敏感，并且有可能成为实时探测纳米尺度结构变化的一种极好的工具，作为一种新的光谱模态。
