Special Issue Information

Dear Colleagues,

Laser-assisted synthesis and processing techniques, such as pulsed laser ablation, laser-induced chemical vapor deposition, and laser-assisted photothermal reactions, offer unprecedented precision and control, enabling scientists to engineer nanomaterials with tailored properties and functionalities. By harnessing laser-induced techniques, researchers have achieved remarkable progress in controlling nanomaterials' size, shape, composition, and surface modifications, leading to innovative applications in various fields, including catalysis, photonics, sensing, and medicine. The interaction between laser beams and nanomaterials at the atomic and molecular levels opens doors to novel material compositions and previously unattainable structures.

We invite leading experts to offer a comprehensive overview of the state-of-the-art laser-assisted synthesis and processing of nanomaterials. Topics of interest include laser ablation, laser annealing, and laser-induced growth. This collection of articles aims to provide insights into the fundamental aspects and practical applications of laser-assisted synthesis, fostering collaboration and innovation in this rapidly evolving field.

Pulsed laser ablation in liquids (PLAL) is a versatile technique to produce high-purity colloidal nanoparticles. Despite considerable recent progress in increasing the productivity of the technique, there is still significant demand for a practical, cost-effective method for upscaling PLAL synthesis. Here we employ and unveil the fundamentals of multi-beam (MB) PLAL. The MB-PLAL upscaling approach can bypass the cavitation bubble, the main limiting factor of PLAL efficiency, by splitting the laser beam into several beams using static diffractive optical elements (DOEs). A multimetallic high-entropy alloy CrFeCoNiMn was used as a model material and the productivity of its nanoparticles in the MB-PLAL setup was investigated and compared with that in the standard single-beam PLAL. We demonstrate that the proposed multi-beam method helps to bypass the cavitation bubble both temporally (lower pulse repetition rates can be used while keeping the optimum processing fluence) and spatially (lower beam scanning speeds are needed) and thus dramatically increases the nanoparticle yield. Time-resolved imaging of the cavitation bubble was performed to correlate the observed production efficiencies with the bubble bypassing. The results suggest that nanoparticle PLAL productivity at the level of g/h can be achieved by the proposed multi-beam strategy using compact kW-class lasers and simple inexpensive scanning systems.
