The advancement of laser technology has been in the last decades significantly supported the European Union, which has provided essential frames for collaborative research projects. This has facilitated major breakthroughs, from fundamental research to the development of advanced technologies for new products and processes.

This presentation outlines the chronological progress of laser technology through three consecutive European projects: Laser4Fun, Lampas, and CLASCO. Laser4Fun initiated efforts in laser-based manufacturing by concentrating on fundamental scientific research. The project focused on laser surface structuring, aiming to uncover the core principles of laser-material interactions. This work laid a strong foundation for the following projects by enhancing the understanding of laser processing complexities.

Building on the findings from Laser4Fun, the Lampas project advanced the application of laser technologies in surface functionalization. Key technological achievements included the use of a >1 kW picosecond laser source, high-speed beam deflection systems (polygon scanners), and Direct Laser Interference Patterning (DLIP). The project also tackled challenges in real-time monitoring, pushing forward both scientific exploration and technological application with a focus on quality assurance.

The CLASCO project continues this trajectory, focusing on the latest laser technology applications in surface engineering. It explores both laser polishing for surface finishing and surface functionalization through microstructuring (DLIP). The introduction of laser polishing adds a new focus, enhancing surface properties through precise laser-induced changes. CLASCO takes a comprehensive approach, combining scientific inquiry with technological innovation to improve surface engineering techniques.
