Abstract: Disclosed is a method for creating a mark desired properties on an anodized specimen and the mark itself. The method includes providing a laser marking system having a controllable laser pulse parameters, determining the laser pulse parameters associated with the desired properties and directing the laser marking system to mark the article using the selected laser pulse parameters. Laser marks so made have optical density that ranges from transparent to opaque, white color, texture indistinguishable from the surrounding article and durable, substantially intact anodization. The anodization may also be dyed and optionally bleached to create other colors.

Abstract: A laser processing system includes a first positioning system (1044) for imparting first relative movement of a beam axis along a beam trajectory (1062) with respect to a workpiece (1060), a processor for determining a second relative movement of the beam axis (1061) along a plurality of dither rows, a second positioning system (1042) for imparting the second relative movement, and a laser source (1046) for emitting laser beam pulses. The laser beam pulses of individually selected energies can be directed to individually selected transverse spot locations (5310) one or more times during a primary laser pass to permit three-dimensional patterning. The laser beam pulses can also be directed to the spatially identical, overlapping, or non-overlapping neighboring spot area locations on the workpiece in a temporally nonsequential order.

Abstract: Methods and apparatus for separating substrates are disclosed, as are articles formed from the separated substrates. A method of separating a substrate having first and second surfaces includes directing a beam of laser light to pass through the first surface and, thereafter, to pass through the second surface. The beam of laser light has a beam waist located at a surface of the substrate or outside the substrate. Relative motion between the beam of laser light and the substrate is caused to scan a spot on a surface of the substrate to be scanned along a guide path. Portions of the substrate illuminated within the spot absorb light within the beam of laser light so that the substrate can be separated along the guide path.

Abstract: Numerous embodiments of methods and apparatus for marking articles are disclosed. In one embodiment, a method of marking an article includes providing an article having a preliminary visual appearance; modifying a region of the article; and directing a plurality of optical pulses into the modified region of the article. The plurality of optical pulses can be configured to produce a visible mark on the article. Generally, the mark can be characterized as having a modified visual appearance different from the preliminary visual appearance.
