In a new Cluster publication, Doctoral Researchers Pascal Rietz, Sebastian Kalt, Jonathan Ludwig Günter Schneider, Postdoctoral Researcher Paul Somers, Alumnus Pascal Kiefer, and PI Martin Wegener have developed a groundbreaking approach for 3D laser nanoprinting. They combined two-step absorption with dynamic multi-focus control, enabling high-resolution printing with up to 31 simultaneous laser foci. This method significantly improves the speed and scalability of 3D nanoprinting by replacing slow single-focus writing with simultaneous multi-focus control. Using compact continuous wave lasers and low power thresholds, they provide a cost-effective alternative to conventional femtosecond laser-based systems.
