Optics Express, 2017 We study the fabrication of photonic surface structures in single crystal diamond by means of highly controllable direct femtosecond UV laser induced periodic surface structuring. By appropriately selecting the excitation wavelength, intensity, number of impinging pulses and their polarization state, we demonstrate emerging high quality and fidelity ...

Advanced Materials Technologies, EarlyView.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
Laser &Photonics Reviews, EarlyView.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.
