Digital tools for laser parameters optimization in femtosecond processing (Conference Presentation)

Based on a simplified ablation model using only two parameters to describe a material, we have developed a numerical method of inverse computation to obtain the most judicious laser configurations for a given depth of ablation in a given material. The calculations are carried out for more than one million configurations (pulse energy, pulse rate, spot diameter, scan speed, …). The results are stored and analyzed on demand via multiple input tables. The digital tools are validated for stainless steel, and ablation results will also be presented for other metals (aluminum, titanium) or composite materials (CFRP).
