High precision patterning of biomaterials using the direct laser interference patterning technology

, 2022
S.3-33Materials used for medical applications may be modified and functionalized by using the direct laser interference patterning method. Thereby, periodic patterns such as lines, pillars, and lamellas can be fabricated on, eg, titanium and polystyrene (

Formation of an anisotropy lattice in Co/Pt multilayers by direct laser interference patterning

Journal of Applied Physics, 2006
We report on the use of direct laser interference patterning to form an “anisotropy” lattice in Co/Pt thin film multilayers. Co/Pt multilayers have been extensively studied and, for the compositions studied here, are characterized by strong perpendicular

Development of an Analytical Model for Optimization of Direct Laser Interference Patterning [PDF]

Materials, 2020
Direct laser interference patterning (DLIP) has proven to be a fast and, at the same time, high-resolution process for the fabrication of large-area surface structures. In order to provide structures with adequate quality and defined morphology at the fastest possible fabrication speed, the processing parameters have to be carefully selected.

Scanner‐Based Direct Laser Interference Patterning on Stainless Steel [PDF]

Advanced Engineering Materials, 2021
Direct laser interference patterning (DLIP) so far has been used almost exclusively in combination with mechanical translation stages reaching impressive throughputs for very specific configurations. As an alternative, DLIP modules can be combined with laser scanners, however presenting some limitations in comparison with standard static optical setups

Influencing the contact angle during brazing by direct laser interference structured textures on the substrate surface

Materials Letters: X, 2022
Direct Laser Interference Patterning (DLIP) is used to generate textured stainless steel surfaces to control the wettability of a liquid nickel-based brazing alloy. The interference of two laser beams leads to periodic line-like structures with a spatial
