Photonic Process Chain for efficient ultrashort pulse surface texturing
Industrial laser texturing is currently still dominated by nanosecond lasers. New approaches show that by means of ultrafast laser sources the productivity of nanosecond lasers is exceeded by a factor of 4 while maintaining the same quality. A removal rate of up to 20 mm³/min with a surface roughness of Ra = 1.5 µm can be achieved. Even roughnesses of < 0.5 µm can be achieved with a ablation rate of up to 10 mm³/min. The photonic process chain shows that with the universal tool of an ultrafast laser, subsequent processes such as cleaning and polishing can also be carried out in the same machinery without time-consuming set-up or re-clamping of the workpiece.
