Direct Laser Interference Patterning (DLIP) is a laser-based technique for generating periodic surface structures with high spatial frequencies. Through this targeted structuring, surface functionalities can be tailored with respect to tribological properties, wettability, hydrophobicity, optical functionality, antibacterial effects, or biocompatibility.
Since DLIP can be applied to a wide range of materials and enables the realization of very different structure sizes and patterns using nanosecond, picosecond, or femtosecond lasers, the process is becoming increasingly relevant for industrial applications.
Against this background, the Laser Technology („Lasertechnologie“) Focus Group of the Optence e. V. network, in cooperation with TOPAG Lasertechnik, will host an online lecture series on DLIP on May 20, 2026. The event will take place from 2:00 pm to 3:30 pm (CET) and will feature three technical presentations:
– Periodic structures created by laser interference irradiation
Dr. Peter Simon, Institut für Nanophotonik Göttingen e. V.
– Online Monitoring during DLIP for Process Control and Texture Quality Prediction
Dr. Marcos Soldera, Technische Universität Dresden
– Functional Metasurfaces by ELIPSYS – Engineering Surface Intelligence at Industrial Scale
Dr.-Ing. Daniel Müller, SurFunction GmbH
Following the presentations, there will be an opportunity for questions and professional exchange. Program details and and free registration are available via the link below.
