Double-Pulse Femtosecond Laser Fabrication of Highly Ordered Periodic Structures on Au Thin Films Enabling Low-Cost Plasmonic Applications

We are thrilled to announce that researchers from the Institute of Electronic Structure and Laser (IESL-FORTH), in collaboration with the University of Manchester and Aix Marseille University, have developed a groundbreaking method to create highly ordered periodic structures on thin gold films using double-pulse femtosecond lasers.

📌 Using pulses just 170 femtoseconds long, this single-step laser technique enables large-area fabrication of plasmonic arrays—perfect for biosensing and other advanced photonic applications—without relying on expensive, time-consuming methods such as conventional electron beam lithography.


👥 The study is a result of international collaboration between Institute of Electronic Structure & Laser (IESL) – Foundation for Research and Technology – Hellas, The University of Manchester, and @Aix Marseille University.
