Abstract: The invention is a method and apparatus for laser marking a stainless steel specimen with commercially desirable marks. The method includes providing a laser processing system having a laser, and laser optics and a controller with pre-determined laser pulse parameters, selecting the pre-determined laser pulse parameters associated with the desired mark, and directing the laser marking system to produce laser pulses having laser pulse parameters associated with the desired marks including temporal pulse widths greater than about 1 and less than about 1000 picoseconds.

Abstract: Laser output (114) is employed to mark an article (100) including a layer (104) supported by a substrate (102), wherein the layer (104) has a thickness (t) that is less than or equal to 50 microns. The laser output (114) is focused to a numerical aperture diffraction-limited spot size (32) of less than or equal to 5 microns at a focal point (80) of the beam waist (90) and directed into the layer (104) to form a plurality of structures comprising a plurality of laser-induced cracks within the layer (104) and within a region of the article (100), wherein the laser-induced cracks terminate within the layer (104) without extending to the substrate (102) or an outer surface (108) of the layer (104), and wherein the plurality of structures are configured to scatter light incident upon the article (100).
