The sample was marked with a 10-watt q-switched ytterbium fiber laser with a 160 mm focal length lens. The 160mm focal length lens has a working distance of 176mm from lens to part. The sample was surface annealed to create a contrasting mark. Painted Brass and Anodized Aluminum are the materials that provided the greatest contrast when marked.
