The part was laser marked with a 20 watt q-switched ytterbium fiber laser with a 160 mm focal length lens. This sample was annealed, or surface marked, to create bright contrast between the material and the mark. This process used the laser at a setting of 16 Watts, with a frequency of 80kHz, and speed of 4 inches per second. The cycle time for processing this part was 2.53 seconds.
