Laser-Induced Periodic Surface Structures (LIPSS) on Polymers Processed with Picosecond Laser Pulses [PDF]

Journal of Laser Micro/Nanoengineering, 2018
Based on a literature review, it was concluded that Laser-induced Periodic Surface Structures (LIPSS) on polymers are produced when applying laser sources operating either in the ultraviolet wavelength and nanosecond pulse duration, or radiation of ...

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

Dynamics of Sliding Friction between Laser-Induced Periodic Surface Structures (LIPSS) on Stainless Steel and PMMA Microspheres.

ACS Applied Materials & Interfaces, 2023
In this work, we investigated the sliding friction measured between poly(methyl methacrylate) (PMMA) colloidal probes with two different diameters D (1.5 and 15 μm) and laser-induced periodic surface structures (LIPSS) on stainless steel with ...

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

Formation of laser-induced periodic surface structures (LIPSS) on tool steel by multiple picosecond laser pulses of different polarizations

Applied Surface Science, 2016
Abstract Laser-induced periodic surface structures (LIPSS) are produced on cold work tool steel by irradiation with a low number of picosecond laser pulses. As expected, the ripples, with a period of about 90% of the laser wavelength, are oriented perpendicular to the laser polarization.

High-speed Laser-Induced Periodic Surface Structures (LIPSS) generation on stainless steel surface using a nanosecond pulsed laser

Surface and Coatings Technology, 2018
Laser Induced Periodic Surface Structures (LIPSS) can be reliably produced using ultra-short laser pulses from 10 fs up to 10 ps, though it is a very time-consuming process.

Femtosecond Laser-Induced Periodic Surface Structures on Different Tilted Metal Surfaces

Nanomaterials, 2020
Laser-induced periodic surface structures (LIPSS) are used for the precision surface treatment of 3D components. However, with LIPSS, the non-normal incident angle between the irradiated laser beam and the specimen surface occurs. This study investigated
