Large-Area Laser Marking Methods Based on Femtosecond Laser Filamentation
In the conventional laser marking systems, the marking area is usually limited due to the short focal length. Herein, an alternative method is proposed to pursue large-area marking based on femtosecond laser filamentation, and the marking range and resolution are analyzed in detail. The experimental results show that the femtosecond laser filamentation can effectively increase the focal depth and complete marking on large-area flat or curved surface samples. Furthermore, the resolution uniformity is improved within the effective working range of the marking system.
