Abstract
The invention is a method and apparatus for creating marks on an anodized aluminum specimen with selectable color and optical density. 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. The laser marking system is directed to produce laser pulses having laser pulse parameters associated with the desired color and optical density in the presence of a fluid directed to the surface of the anodized aluminum specimen while marking.
