KrF 准分子激光束用于在不同的加工条件下在不锈钢表面上产生可控的高对比度颜色。激光束充当局部加热源，促进样品表面上不同厚度和形态的半透明氧化膜的形成。通过研究氧化膜的表面形态和光学特性及其厚度，采用椭圆光度术和原子力显微镜来了解激光引起的颜色。研究发现，激光诱导的颜色随氧化层厚度的变化而变化。激光处理区域具有颗粒结构，会影响氧化物生长和光散射。
A KrF excimer laser beam is used to induce controllable and high-contrast colors on a stainless-steel surface under different processing conditions. The laser beam acts as a localized heating source that promotes the formation of semitransparent oxide films of varying thicknesses and morphologies on the sample surface. Ellipsometry and atomic force microscopy were employed to understand the laser-induced colors by studying the surface morphology and optical properties of the oxide films and their thickness. It is found that the laser-induced colors vary with the oxide layer thickness. The laser-treated areas have granular structures, which affect oxide growth and light scattering.
