Abstract

Femtosecond lasers are key to modern precision manufacturing in the display, semiconductor, and medical industries. This lecture will cover the basics of ultrafast laser-matter interaction and resulting processes like drilling, cutting, and surface/in-volume modification. Participants will learn about material excitation and ablation, focusing on the critical role of laser pulse duration, wavelength, and spatiotemporal shaping on the processing outcome. Selected innovative laser process examples will be demonstrated.
