Abstract (en)
[origin: WO2012121732A1] Disclosed is a method for creating a mark 152 with desired properties on an anodized specimen 150 and the mark 152 itself. The method includes providing a laser marking system 10, 12, 14, 16 18, 20, 22 having controllable laser pulse parameters, determining the laser pulse parameters associated with the desired properties and directing the laser marking system 10, 12, 14, 16 18, 20, 22 to mark the article 18 using the selected laser pulse parameters. Laser marks 162 so made have optical density that ranges from transparent to opaque, white color, texture indistinguishable from the surrounding article and durable, substantially intact anodization 160. The anodization 120 may also be dyed and optionally bleached to create other colors 136, 144.
