Laser micro-processing is a research field and technological approach focused on the precise manipulation and modification of materials at the micro-scale using highly focused laser beams. It investigates the fundamental light-matter interactions and develops methods for localized material processing. This encompasses a range of techniques including ablation, cutting, drilling, welding, marking, and surface structuring, characterized by high spatial resolution, non-contact interaction, and versatility across diverse materials. Its significance is rooted in enabling the fabrication of complex micro-features critical for advanced manufacturing, medical devices, electronics, and other high-precision applications.
