We are witnessing that ultrashort laser material processing (ULMP) is getting an established technique to modify many characteristics of a surface. Being applicable for various materials with any geometry or physical characteristics, besides being rapid and having simple experimental set-ups makes ULMP appropriate for small and large scale controlled modifications. Using this method to adjust the optical features of a surface has been also suggested in last years. So that mimicking the functional surfaces existing in nature which have distinctive surface morphologies and thus have special optical features, efforts are going on to create similar samples using ULMP. Here in this study, the potential of ULMP technique in changing the optical properties of metallic substrates is explored. Selecting 316L stainless steel as a substrate, five samples which are irradiated in different circumstances are fabricated. The role of the laser induced nano/micro structures on the optical featur...

飞秒激光诱导的纳米/微观结构对钢表面光学特性的作用；实验极化法研究

我们目睹了超短激光材料加工（ULMP）正在获得一种可改变表面许多特征的成熟技术。除了快速且具有简单的实验设置外，ULMP还适用于具有任何几何形状或物理特性的各种材料，这使得ULMP适合于小规模和大规模的受控修改。近年来还建议使用这种方法来调节表面的光学特征。为了模仿自然界中存在的功能表面，这些功能表面具有独特的表面形态并因此具有特殊的光学特征，因此正在努力使用ULMP来创建类似的样品。在此研究中，探讨了ULMP技术在改变金属基板光学特性方面的潜力。选择316L不锈钢作为基材，制作了五个在不同情况下照射的样品。激光诱导的纳米/微结构在光学特性上的作用
