The part was laser marked with a 10-watt q-switched ytterbium fiber laser and a 160 mm focal length lens. The part was surface annealed using 3 watts of power, to create a contrasting mark. The part was marked at a speed of 15 inches per second with a frequency of 40 kHz, resulting in a cycle time of 0.49 seconds per 2D Matrix. The codes were readable in our applications laboratory.
