Abstract

The employment of pulsed lasers offers a novel unique tool for nanofabrication [1]. When focused on the surface of a solid target, pulsed laser radiation causes a variety of phenomena, including heating, melting, and finally ablation of the target, and such processes can lead to an efficient material nanostructuring. First, the laser-assisted removal of material from the irradiated spot can result in a spontaneous formation of variety of periodic nanoarchitectures within this spot. Second, laser ablation of material from a solid target leads to the production of nanoclusters, which can then be either deposited on a substrate to form a nanostructured film or released into a liquid environment to form a colloidal nanoparticle solution. Our on-going projects on laser nanofabrication include the following activities:
