Read my LIPSS: organic lasers on micromachined resonators [PDF]

Nature Communications
Thin-film lasers based on organic semiconductors offer significant potential for miniaturized sensing and optical memory. We present a new method for creating first-order distributed feedback (DFB) Bragg gratings using laser-induced periodic surface ...

Bessel beam generated LIPSS on NiTi wires [PDF]

Applied Physics A, 2023
AbstractUltrashort laser pulses are used to generate Laser-Induced Periodic Surface Structures (LIPSS). To apply LIPSS on small confined areas, the laser source must be focused to a small spot diameter. Contrary to commonly used high numerical aperture objectives, we present a Bessel beam-based approach to produce LIPSS covered lines with a width of 4 ...

Liquid vortexes and flows induced by femtosecond laser ablation in liquid governing formation of circular and crisscross LIPSS

Opto-Electronic Advances, 2022
Orientations of laser induced periodic surface structures (LIPSS) are usually considered to be governed by the laser polarization state. In this work, we unveil that fluid dynamics induced by femtosecond (fs) laser ablation in liquid (fs-LAL) can easily ...

Mechanism of Tailoring Laser-Induced Periodic Surface Structures on 4H-SiC Crystal Using Ultrashort-Pulse Laser [PDF]

Nanomaterials
In this study, we examine the characteristics of laser-induced periodic surface structures (LIPSSs) fabricated on N-doped 4H-SiC (N-SiC) and high-purity 4H-SiC (HP-SiC) crystals using femtosecond–picosecond lasers. The effects of various laser parameters

Influence of unidirectional polishing on the formation of laser-induced periodic surface structures on steel [PDF]

Scientific Reports
We have performed a detailed analysis of the dependence of the regularity of laser-induced periodic surface structures (LIPSS) on the surfaces of steel samples that have been ground (polished) to achieve unidirectional surface roughness.

LIPSS for metal forming tools [PDF]

PhotonicsViews, 2021
AbstractFrom ecological and economic points of view, alternatives to conventional lubricants in metal forming are of great interest. The focus is on tools' surface functionalization by laser‐induced periodic surface structures (LIPSS). These structures must be protected due to their loss when in direct tribological contact.
