  • Patent number: 11130195
    Abstract: A laser ablation process can be configured to reduce the appearance of or eliminate a potentially objectionable diffraction effect that can occur when a workpiece or product that has been subjected to the ablation process interacts with light. The diffraction effect can be reduced by introducing irregularity into the arrangement of overlapping laser spots during the process. Other process parameters may be modified to reduce the diffraction effect, such as laser scan speed, laser pulse frequency, the position of the focal plane of the laser, the configuration of raster lines, or the energy profile of the laser beam, for example. The process modifications and configurations are particularly useful with products including an ablated surface that is intended to reflect light or to allow light to pass therethrough as part of its function.

  • Patent number: 11126056
    Abstract: A method for removing a material from a surface of a substrate includes impinging a laser beam on the material during a first sweep to remove the material from the surface along a first line and impinging the laser beam on the material during a second sweep to remove the material from the surface along a second line adjacent to the first line. The first line includes first artifacts that form a first portion of an array of artifacts on the surface. The second line includes second artifacts that form a second portion of the array of artifacts on the surface. A first laser pulse of the laser beam corresponding with the second sweep is synchronized with a start of the second sweep when transitioning between the first line and the second line such that the start of the second sweep coincides with the first laser pulse.
