Abstract
The invention is a method and apparatus for creating a color and optical density selectable visible mark on an anodized aluminum specimen. The method includes providing a laser marking system having a laser, laser optics and a controller operatively connected to said laser to control laser pulse parameters and a controller with stored laser pulse parameters, selecting the stored laser pulse parameters associated with the desired color and optical density, directing the laser marking system to produce laser pulses having laser pulse parameters associated with the desired color and optical density including temporal pulse widths greater than about 1 and less than about 1000 picoseconds to impinge upon said anodized aluminum.
