Abstract

One of the current trends of laser applications in material science is using high-intensity lasers to provide fast and efficient surface or volume modifications for achieving controllable material properties, synthesis of novel materials with desired functionalities, and upscaling laser technologies with industry-demanded throughputs. Depending on the parameters, lasers can offer versatile solutions for scientific and industrial applications, starting from exploring the fundamental physics of warm dense matter and molecular chemistry at ultrashort timescales to large-scale fabrication of surfaces with anti-bacterial, tribological, hydrophobic, or hydrophilic properties. The objectives of this Chapter are to provide a review of recent advancements in several laser application fields, which involve high-intensity lasers, both ultrashort (femto- and picosecond) and short (nanosecond). After summarizing general trends in high-intensity laser processing of materials, we will first focus on the new opportunities offered by high-intensity lasers for the controlled synthesis of multielement nanoparticles for catalytic and theranostic applications. Then, the blister-based laser-induced forward transfer (BB-LIFT) technique will be presented, allowing a one-step, high-precision printing of nanomaterials on any substrates. The next section will discuss the selective crystallization of amorphous (as prepared) semiconductor nanoscale materials. The processes enabling high selectivity of crystallization into the desired phase using ultrashort powerful lasers will be analyzed. After that, opportunities for using high-power lasers will be discussed for upscaling surface nanostructuring with high throughput for bio-medical and industrial applications. Finally, an introduction to the Open Access program of the HiLASE Centre, which is targeted at offering users high-intensity beam time, will be given.
