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

Hierarchical Micro-/Nano-Structures on Polycarbonate via UV Pulsed Laser Processing
Hierarchical micro/-nanostructures were produced on polycarbonate polymer surfaces by employing a two-step UV-laser processing strategy based on the combination of Direct Laser Interference Patterning (DLIP) of gratings and pillars on the microscale (3 ...

Microstructures fabricated by two‐beam DLIP combining spatial‐period and roughness gradients are fabricated to enhance directional transport of water droplets. The coupled gradients increase transport distance by 160% and strongly suppress motion against the gradient, demonstrating an effective strategy for controlled droplet manipulation.

Transient Laser‐Induced Periodic Surface Structures Revealed by Time‐Resolved EUV Diffuse Scattering
The study shows that femtosecond laser pulses generate transient, LIPSS‐like surface patterns at fluences far below the damage threshold. Time‐resolved extreme ultraviolet scattering captures reciprocal space features that form within a few picoseconds and vanish on sub‐nanosecond timescales.

Dynamical studies on the generation of periodic surface structures by femtosecond laser pulses
The dynamics of the formation of laser-induced periodic surface structures (LIPSS) on fused silica upon irradiation with linearly polarized fs-laser pulses (50 fs pulse duration, 800 nm center wavelength) is studied experimentally using a double pulse ...
