Special Issue Information

Dear Colleagues,

This Special Issue is dedicated to the 70th birthday of Jürgen Reif, retired full professor, former Chair of Experimental Physics II of the Faculty of Physics of the Brandenburg University of Technology Cottbus—Senftenberg in Germany.

In recognition of his long-lasting scientific contributions and research lines, the topics of this Themed Special Issue are defined and include nonlinear optics and photonics, semiconductor technology, optical spectroscopy, surface dynamics, in situ measurement techniques, experimental and theoretical investigations of laser–matter interaction, applications of surface functionalization through laser-induced micro- and nanostructures, laser processing of polymers, numerical modeling of surface processes, etc.

For more than 25 years, the work of Prof. Reif has been very actively devoted to the study of fundamental mechanisms, dynamics, and applications of nano- and micrometer-scale laser-induced periodic surface structures (LIPSS), with a focus on self-organization processes. His contributions have revived and strongly stimulated the competition of the two main approaches (“schools”) to explain LIPSS, either via matter reorganization or via coherent electromagnetic scattering effects, and investigated their dynamics and applications in the fields of surface wetting and tribology.

Because these scientific areas lie at the boundaries between nonlinear optics and spectroscopy, surface and solid state physics, materials science and nanotechnology, and in honor and recognition of Prof. Reif’s scientific contributions, this joint Special Issue of the two journals Molecules and Nanomaterials welcomes the submission of original research manuscripts, perspectives articles, or reviews related to "Dynamics and Processes at Laser-irradiated Surfaces".

Accepted papers are published in the joint Special Issue in Molecules or Nanomaterials (https://0-www-mdpi-com.brum.beds.ac.uk/journal/nanomaterials/special_issues/Laser-irradiated-Surfaces-Juergen-Reif).

The efficiency of light coupling to surface plasmon polariton (SPP) represents a very important issue in plasmonics and laser fabrication of topographies in various solids. To illustrate the role of pre-patterned surfaces and impact of laser polarisation in the excitation of electromagnetic modes and periodic pattern formation, Nickel surfaces are irradiated with femtosecond laser pulses of polarisation perpendicular or parallel to the orientation of the pre-pattern ridges. Experimental results indicate that for polarisation parallel to the ridges, laser induced periodic surface structures (LIPSS) are formed perpendicularly to the pre-pattern with a frequency that is independent of the distance between the ridges and periodicities close to the wavelength of the excited SPP. By contrast, for polarisation perpendicular to the pre-pattern, the periodicities of the LIPSS are closely correlated to the distance between the ridges for pre-pattern distance larger than the laser wavelength. The experimental observations are interpreted through a multi-scale physical model in which the impact of the interference of the electromagnetic modes is revealed. Full article

Ultrafast lasers micromachining results depend on both the processing parameters and the material properties. The obtained thermal effects are negligible if a good combination of processing parameters is chosen. However, optimizing the processing parameters leading to the required surface quality on a given material can be quite complex and time consuming. We developed a semi-empirical model to estimate the heat accumulation on a surface as a function of the laser fluence, scanning speed and repetition rate. The simulation results were correlated with experimental ones on different materials, and compared with the transient temperature distributions calculated using an analytical solution to the heat transfer equation. The predictions of the proposed model allow evaluating the heat distribution on the surface, as well as optimizing the ultrafast laser micromachining strategy, yielding negligible thermal damage.
