Study on the Origin and Evolution of Femtosecond Laser-Induced Surface Structures: LIPSS, Quasi-Periodic Grooves, and Aperiodic Micro-Ridges

Materials, 2023
We investigate the evolution mechanisms of the laser-induced periodic surface structures (LIPSS) and quasi-periodic grooves that are formed on the surface of monocrystalline silicon (mono-Si) when exposed to femtosecond laser radiation of different pulse duration, state of polarization, and fluence.

Sub-Diffraction Limited Writing based on Laser Induced Periodic Surface Structures (LIPSS). [PDF]

Sci Rep, 2016
AbstractControlled fabrication of single and multiple nanostructures far below the diffraction limit using a method based on laser induced periodic surface structure (LIPSS) is presented. In typical LIPSS, multiple lines with a certain spatial periodicity, but often not well-aligned, were produced.

Formation of Laser-Induced Periodic Surface Structures (LIPSS) on Dielectrics and Semiconductors upon Double-Femtosecond Laser Pulse Irradiation Sequences

, 2014
The formation of laser-induced periodic surface structures (LIPSS) on different materials (silicon, fused silica, quartz) with linearly polarized fs-laser irradiation is studied experimentally. In dielectrics, the importance of transient excitation stages in the LIPSS formation is demonstrated by using (multiple) cross-polarized double-fs-laser-pulse ...

Tracing the Formation of Femtosecond Laser-Induced Periodic Surface Structures (LIPSS) by Implanted Markers. [PDF]

ACS Appl Mater Interfaces
The generation of laser-induced periodic surface structures (LIPSS) using femtosecond lasers facilitates the engineering of material surfaces with tailored functional properties. Numerous aspects of their complex formation process are still under debate, despite intensive theoretical and experimental research in recent decades.

Mechanical and optical effects of laser-induced periodic surface structures (LIPSS) on carbon fibres and composites

JPhys Materials
Laser-induced periodic surface structures (LIPSS) have been employed extensively across many fields of materials surface engineering. LIPSS have previously been demonstrated on carbon fibre materials in literature, yet the impact these treatments have on

Fractal Dimension and Texture Analysis in the Assessment of Experimental Laser-Induced Periodic Surface Structures (LIPSS) Dental Implant Surface-In Vitro Study Preliminary Report. [PDF]

Materials (Basel), 2022
Laser-induced periodic surface structures (LIPSS) are the sub-wavelength periodic nanostructures generated by the femtosecond laser. Implant topography and its nanostructural changes can be important for biomedical applications. In order to compare the surface topography of different implants, appropriate mathematical and physical descriptive methods ...

Two-Dimensional Periodic Nanostructure Fabricated on Titanium by Femtosecond Green Laser

Nanomaterials, 2020
Laser-induced periodic surface structures (LIPSS) is the sub-wavelength periodic nanostructure, which is generally generated by the femtosecond laser. There are two kinds of LIPSS, low spatial frequency LIPSS (LSFL) and high spatial LIPSS (HSFL), and the

Upscaling laser-induced periodic surface structures (LIPSS) manufacturing by defocused laser processing [PDF]

Laser-based Micro- and Nanoprocessing XIII, 2019
Low spatial frequency Laser-induced Periodic Surface Structures (LSFL) have been created on single crystal silicon with picosecond laser pulses with a wavelength of λ =1030nm with varying laser spot diameters obtained by a defocused laser beam. The laser processing parameters have been adjusted theoretically and experimentally to obtain similar LSFL ...
