Lecture
This lecture covers the principles of laser ablation, including the ablation model, pulsed laser ablation, and single pulse ablation. It also discusses the interaction of 193 nm Excimer light with materials and the physical model behind ablation depth. Furthermore, it delves into laser bending techniques, such as heating-counterbending and cooling-positive bending, as well as laser welding methods, including fixation by laser welding and conduction welding. The lecture explores different types of lasers used in materials processing, such as Nd:YAG lasers and fiber lasers, and their applications in bending, welding, and soldering processes.
