通过飞秒激光加工在材料表面形成的纳米和微米尺度结构极大地改变了材料的光学特性、润湿性以及其他性质。本文报道了利用飞秒激光在球形铝表面上形成纳米和微米尺度的结构，发现飞秒激光处理后的表面在紫外到红外（0.2-2.5 μm）范围内具有很强的光捕获能力。我们的结果表明，这种方法可以用来处理一个球面没有复杂的4轴样品控制，并在原则上，它适用于任何非平面样品。
Nano- and microscale structures on a material surface formed by femtosecond laser processing have greatly changed optical characteristics, wettability, as well as other properties of the material. In this work, we report the formation of nano- and microscale structures on a spherical Al surface with femtosecond laser filament, and find that the filament-processed surface has a strong light-trapping ability from UV to IR (0.2–2.5 μm). Our result demonstrates that this method can be used to process a spherical surface without the complexity of a 4-axis sample control, and in principle, it is applicable to any non-planar sample.
