Periodic nanostructures with a period of about 100–150 nm are formed on the surface of nanoporous silicate glass irradiated by sharply-focused laser pulses with a wavelength of 515 nm and a duration of 300 fs and are visualized by scanning electron microscopy. The reflection/transmission spectroscopy of the formed nanostructures in the visible range reveals their antireflection effect.

飞秒可见光激光脉冲辐照纳米多孔玻璃表面纳米光栅的形成

在波长为 515 nm、持续时间为 300 fs 的锐聚焦激光脉冲照射下,在纳米多孔硅酸盐玻璃表面形成周期约为 100-150 nm 的周期性纳米结构,并通过扫描电子显微镜观察。形成的纳米结构在可见光范围内的反射/透射光谱揭示了它们的抗反射作用。
