Achieve desired results with short pulse durations
Shortened pulse durations can be set with a MOPA laser machine, which is the key to creating black marks on anodized aluminum. With this process, the short pulse durations repaints the material but does not remove the anodized layer or damage the surface. This technique is comparable to the production of tempering colors on stainless steel, but different in its own way. The filling line distance can be set to adjust in a wide range of varying shades from grays up to deep and rich black: The smaller the distance, the deeper the marked color becomes.
