介绍了采用中心波长为800 nm的飞秒激光在不锈钢(316L)表面诱导产生独立显示图案的研究。结果表明，当扫描速率为15 mm/s，扫描行距为20 μm，能量密度为1.1 J/cm2时，飞秒激光能够在不锈钢表面形成均匀的周期为540 nm的亚波长条纹结构。利用条纹结构的方向与激光光波偏振方向严格垂直的特性，通过改变激光偏振，可以在金属表面形成不同方向的条纹图案。在照明白光的辐照下，改变样品的方位角，形成的图案能够以彩色方式显示出来。此外，对使图案彩色显示的坐标区域与图案色彩能够覆盖的可见光谱范围进行了研究，并对其可能的应用进行分析。

In this paper, we demonstrate the exclusive display of the patterns fabricated by femtosecond laser with a central wavelength of 800 nm on the 316L stainless steel surface. The uniform ripple structures with a period of 540 nm can be produced under the laser scanning speed of 15 mm/s, line space of 20 μm and laser energy density of 1.1 J/cm2. The strong dependence of the ripple orientation on the polarization of laser light offers us the opportunity of fabricating different patterns with different types of ripples. By rotating the sample, the patterns can be exclusively observed under the irradiation of the white light from different angles. In addition, the coordinate areas and the spectral ranges for the exclusive display of the patterns are studied. Finally, the potential applications of this technology are illustrated.
