SUMMARY:RIANA Webinar: Additive-Subtractive Synergy in Ultrafast Digital Manufacturing
DESCRIPTION:Title: Additive-Subtractive Synergy in Ultrafast Digital Manufacturing: Tunable Femtosecond-to-Picosecond Laser Processing for Highly Selective Ablation and Printing in Thin-Film Electronics and Photovoltaic Applications. \nSpeaker: Catalin Constantinescu\, CNRS-LP3 (Laserlab-Europe) \nDate: 17 Dec 2025\, 15:00-16:30 Central European Time \nThe convergence of additive and subtractive digital manufacturing is essential for producing multifunctional micro-/ and nano-structured devices with high spatial precision. This talk presents a unified fabrication platform based on a tunable femtosecond-to-picosecond ultrafast laser system\, enabling both highly-selective ablation\, and printing\, to be performed on a single optical setup\, without significant reconfiguration. By tuning the pulse duration from fs to ps\, we access a controlled transition from non-thermal\, electronically driven ablation to thermally assisted material transfer\, providing a powerful degree of freedom in processing hybrid organic/inorganic thin films\, functional multilayers\, and metal nanoparticle inks. This tuneability allows one to engineer selective ablation thresholds\, tailor jet dynamics in printing\, and optimize feature resolution and material integration. Furthermore\, a discussion on how laser-matter selectivity emerges from contrasts in absorption\, bonding energy\, thermal diffusion length\, and layer architecture\, is presented. Time-resolved microscopy and post-process characterization reveal how these parameters govern interface response and deterministic control of etching and printing. Such additive-subtractive synergy opens streamlined pathways for fabricating photonic components\, flexible electronics\, surface sensors\, and lab-on-chip devices\, as well as next-generation photovoltaic architectures\, including organic/inorganic hybrid thin films. These results demonstrate how tunable fs-ps laser processing redefines precision digital manufacturing for scalable functional device integration. \n			\n			\n				\n				\n				\n				\n			\n				\n				\n				\n				\n				\n				\n				Registration\n			\n			\n				\n				\n				\n				\n				\n				About RIANA
