Laser ablation patterning by interference induces directional cell growth
IEEE Transactions on Nanobioscience, 2003Laser-patterning by interference is a method to introduce micropatterns on the surface of TXL and TXB, which were shown to have an effect on the L929 growth. In this experiment, we have produced collagen-coated and laser-patterned TXL and TXB with different dimensions; the groove width of the line patterns varied approximately from 1.2 microm to 9.7 ...

Direct laser interference patterning combined with mask imaging
Optics & Laser Technology, 2020Abstract Direct laser interference patterning (DLIP) is a one step process to produce customized textured surfaces on the micrometer scale. Depending on the laser system, achieving a large area homogeneous pattern can be challenging. Particularly, with nanosecond lasers, an irregular intensity distribution or superposition leads to uneven melting ...

To use or not to use (direct laser interference patterning), that is the question
SPIE Proceedings, 2015Direct Laser Interference Patterning (DLIP) has shown to be a fabrication technology capable of producing large area periodic surface patterns on almost any kind of material. The produced structures have been used in the past to provide surfaces with new enhanced properties.

Plasmonic nanostructuring through direct laser interference patterning
SPIE Proceedings, 2014Direct writing of plasmonic nanostructures is demonstrated by nanoscale-tensile-stress induced patterning through interference crosslinking in a polymer film and by single-pulse interference ablation of a gold film. Nanoscale-tensilestress from the interference crosslinking of polymer films which are exposed to the interference pattern of UV laser ...

Periodic patterning of silicon by direct nanosecond laser interference ablation
Applied Surface Science, 2011Abstract The production of periodic structures in silicon wafers by four-beam is presented. Because laser interference ablation is a single-step and cost-effective process, there is a great technological interest in the fabrication of these structures for their use as antireflection surfaces.

Direct Laser Interference Patterning of Graphene in Contact Lenses
Advanced Engineering MaterialsThis study explores a cost‐effective method for creating nanostructures on contact lenses (CLs) as potential wearable sensors. Using direct laser interference patterning, commercially available CLs are coated with graphene ink and ablated with a neodymium‐doped yttrium aluminum garnet laser at 30 mJ pulse energy and various tilt angles.

We have studied the fabrication of hierarchical periodic microstructures on metals by means of direct laser interference patterning. A nanosecond pulsed Nd:YAG laser at 355 nm wavelength was used to produce the microstructures with grating periods ranging from 1 μm to 10 μm on stainless steel, titanium, and aluminum.

Hierarchical microstructures offer improved surface functionalities or a combination of surface properties compared to single‐scale patterns, e.g., low reflectivity and hydrophobicity. The fabrication of three‐level length‐scales microstructures on polyethylene terephthalate (PET) substrates is demonstrated using UV nanosecond‐pulsed direct laser ...

Direct Laser Interference Patterning of Nickel Molds for Hot Embossing of Polymers
Advanced Engineering Materials, 2016In this study, the authors present a single‐step approach for fabricating micrometer structures on metallic hot embossing molds using direct laser interference patterning. Patterns with spatial periods of 1.8 and 2.5 µm are structured on a Ni‐mold and used for embossing PET‐foils.
