Résumé of Femtosecond laser color marking of metal and semiconductor surfaces This article starts off with an abstract and an introduction. The abstract describes short what is tested. “Color marking of rough or smooth metal (Al, Cu, Ti) and semiconductor (Si) surfaces was realized via femtosecond laser fabrication of periodic surface nanorelief, representing one-dimensional diffraction gratings.” (Ionin, Kudryashov, Makarov, & Seleznev, 2012) It continues with theory of it. In the introduction there is a more elaborated theoretical framework of previous research and an explanation of why “However, this coloration principle lacks homogeneous color brightness, since the nanogratings efficiency will vary for different diffraction angles.” (Ionin, Kudryashov, Makarov, & Seleznev, 2012) And how “spatial color variation across the surface of interest can be provided by changing the actual gratingperiod via variation of the incidence angle θ of the laser radiation with the wavelength λ.” (Ionin, Kudryashov, Makarov, & Seleznev, 2012) they will do this study. The next part is experimental setup and procedures which describes the setup of the experiment (fig 1) and furthermore information, like which microscope they used (Levenhuk BioView 630 or Olympus BX-51) so the reader could replicate this experiment. After the setup there is an experimental results and discussion section which provides information about the nanogratings and nanostructures (fig 2 and 3) and also an more depth analysis of these findings (fig 4-7). The conclusion provides the answers to the introduction which should be demonstrated. It gives a brief what the experiment was about and how they used it and provided the findings “Different bright colors covering the entire visible range, were shown to be provided not by grating rotation on a surface, but via pre-determined angularly controlled variation of surface
