Laser Ablation Process and Mechanism of Advanced Materials Processing

Dear Colleagues,

Laser ablation is one of the most common effects of the interaction of laser radiation with matter. At present, the mechanism of laser ablation is widely used for processing almost all types of materials (e.g., metals, ceramics, polymers, transparent dielectrics, biological tissue in various media), the synthesis and modification of various nanomaterials, and the production of functional nanoparticles.

Currently, non-standard approaches to the implementation of the laser ablation process which allow the use of new mechanisms of action on the material, or lead to previously unknown effects, are of the greatest interest. Such approaches can initiate the formation of new types of micro- and nanostructures with unique physicochemical properties. It is possible to obtain a wide variety of modes of action on a material, leading to the appearance of new structures, composite materials, and functional nanoparticles using a variety of laser sources with different wavelength, power, pulse duration, as well as media in which ablation effects occur.

Such approaches are usually located at the intersection of various scientific fields, or arise from a combination of non-standard solutions or using the latest scientific achievements of laser technology.

This Special Issue focuses on the advanced laser processing of materials, using new non-standard approaches in the choice of media and laser exposure modes.

The topics of interest include, but are not limited to:

• New approaches to the laser ablation of materials in non-standard media (supercritical fluids, solid-state dielectrics, etc.);
• Formation of composite nanomaterials under laser exposure;
• Study of the mechanisms of formation of structures of various scales on the surface of materials during laser ablation in various media;
• Time-resolved studies of laser ablation processes in non-standard media;
• Carrying out the processes of the ablation of various materials using new laser sources, including the far-IR range.

This Special Issue aims to publish papers discussing recent trends in laser ablation processes, primarily using non-standard combinations of materials and laser treatment methods, as well as those identifying new mechanisms of laser action on materials.
