The part was marked using a 20 watt q-switched ytterbium fiber laser with 160 mm focal length lens. The 160mm focal length lens has a working distance of 176mm from lens to part. The ceramic sample was marked twice, using two different sets of parameters. The first mark was processed using 8 watts of power with a frequency of 25 kHz and a speed of 25 inches per second. It resulted in a cycle time of 2.27 seconds and a lighter etched mark. The second mark was created using 12 watts of power, with a frequency of 80kHz, and a speed of 10 inches per second. It resulted in a cycle time of 5.81 seconds and a darker, deeper etched mark.
