Surface Plasmon Polariton Triggered Generation of 1D-Low Spatial Frequency LIPSS on Fused Silica

Applied Sciences, 2018
We report on the generation of low spatial frequency laser-induced periodic surface structures along straight lines on fused silica by spatially scanning the laser parallel to its polarization direction. The influence of the applied laser fluence and the

Laser fluence-dependent LIPSS formed on the surface of niobium alloys [PDF]

EPJ Web of Conferences
Laser fluence-dependent laser-induced periodic surface structures (LIPSS) on niobium alloys was analysed. Additionally, we explored the shift from LIPSS to self-organized, periodic microstructures resembling cones.

Fabrication of Diamond Membranes by Femtosecond Laser Ablation for MEMS Sensor Applications

Proceedings, 2020
We present the feasibility in fabricating membranes and cantilevers made of diamond grown on Si/SiO2 substrates by femtosecond laser ablation. In the ablation process, we generated nano- and microstructures on the membrane surface.

Constructive feedback for the growth of laser‐induced periodic surface structures [PDF]

physica status solidi c, 2016
AbstractWe study the formation and growth of laser‐induced periodic surface structures (LIPSSs) with the finite‐difference time‐domain (FDTD) method. We use a recently proposed inter‐pulse feedback method to account for the evolution of the surface morphology between each laser pulse sent to the surface of the processed material.

Initial Cumulative Effects in Femtosecond Pulsed Laser-induced Periodic Surface Structures on Bulk Metallic Glasses

, 2016
We investigate initial cumulative irradiation effects leading to variable surface topographies and nanoscale roughness, and triggering eventually the formation of laser-induced periodic surface structures (LIPSS) on Zr-based bulk metallic glasses (Zr41.
