Special Issues and Collections in MDPI journals
The study of laser fabricated periodic nanostructures is one of the leading topics of today’s photonics research. Such structures on the surface of metals, semiconductors, dielectrics or polymers can generate new material properties with special functionalities. Depending on the specific material parameters and the morphology of the structures, new devices like microlasers, optical nanoswitches, optical storage devices, biosensors or antifraud features can be realized. Furthermore, surface textures can be used to improve the tribological properties of special tools for the reduction of friction losses or wear, to modify the wettability or the cell and biofilm growth properties of surfaces or as decoration elements for the refinement of precious goods.
This Special Issue focuses on the latest theoretical developments and practical applications of laser-induced periodic surface structures that can be generated in a self-organized way (LIPSS, ripples) or via laser interference ablation. It aims to attract both academic and industrial researchers in order to foster the current knowledge of nanomaterials and to present new ideas for future applications and new technologies.

Abstract: Mid-infrared (MIR) wavelength (2-10 um) opens up a new paradigm in femtosecond laser solid interaction, both from fundamental and applications perspectives. On fundamental level, compared to ubiquitous near-IR (NIR) or visible (VIS) laser interactions, MIR photon energy scale renders semiconductors like Si and Ge to behave like high bandgap materials, while at the same time conduction electrons are driven harder due to \lambda$^2$ scaling of cycle averaged energy, altering energy absorption characteristics. From applications perspective, many materials that are non-transparent to VIS-NIR range, are transparent to MIR wavelengths, allowing patterning, waveguide writing and machining inside these materials, and also extend interaction to higher order multi-photon processes, paving way to finer resolution in materials processing. Here we present the formation of an anomalous extreme sub-wavelength structure formation ($\sim \lambda/50$) on single crystal silicon surface by a 3600 nm MIR femtosecond laser with a pulse duration of 200 fs. The 50-100 nm linear structures were aligned parallel to the laser polarization direction with a quasi periodicity of approx 700 nm. The dependence of the structure on the native oxide, laser pulse number and polarization were studied. The properties of the structures were studied using SEM, HRTEM, EDS. As traditional models for the formation of laser induced periodic surface structure do not explain how these structures form, new theoretical efforts are needed.

Abstract: Laser-induced periodic surface structures (LIPSS) spontaneously appearing on the laser-treated (melted or evaporated) surfaces of bulk solid materials seem to be a well-studied phenomenon. Peculiarities of oxidative mechanisms of LIPSS formation on thin films though are far less clear. In the present work the appearance of oxidative LIPSS on thin titanium films under ns-pulsed Yb-fiber laser action is demonstrated. The temperature and energy regimes favoring to their formation were revealed, and their geometric characteristics were determined. The period of these LIPSS was found to be about 0.6 λ, and their modulation depth varies between 70 and 110 nm. It was shown that in the regimes of our interest LIPSS tend to predominately self-organize perpendicularly to the scanning direction, which could give a simple way to control their properties.
