Lasers & Sources

High-productivity synthesis of ligand-free nanoparticles by laser ablation in liquids
Metal and metal oxide nanoparticles are produced on the gram scale with a novel ablation setup that includes a high-power pulsed-laser system, an ultrafast laser scanner, and a customized ablation chamber.
Optical components move a high-resolution laser-scan pattern contained in a small field of view across a larger area, eliminating the need for heavy steering mechanisms on platforms such as helicopters.
