Abstract:
A method for removing a material from a surface includes passing a laser through a lens such that the laser impinges on the material. The surface from which the material is removed has an array of artifacts thereon with a spacing between the artifacts and a pitch between lines of the artifacts. At least the spacing between the artifacts is varied.
