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. Two passes were required to produce the dark mark using 16 watts of power, with a frequency of 80 kHz and speed of 3 inches per second. The cycle times for the dark mark was 20.24 seconds.
