Fabrication of micro- and nanostructures on polymeric materials is of high interest in technological areas of organic photonics and electronics, biomedicine, bioengineering and sensing.
In pulsed laser deposition (PLD) the material ejected in the ablation plume is deposited on a substrate placed in front of the target as shown in the scheme of the typical set up.
Laser ablation plasmas are complex media characterized by varying degrees of ionization and non-equilibrium states, and their compositional and dynamic analysis is often far from trivial. In our labs at IQFR, we rely on a range of techniques aimed at the description and understanding of these systems:
Our research in this field is centered on the generation of low and high-order harmonics in laser-induced ablation plasmas. These plasmas show interesting properties as nonlinear media, due both to their often complex composition (radicals, clusters, nanoparticles, etc.) and to the possibility of controlling their macroscopic behavior, and thus the phase matching.
The Laser Laboratory for Heritage Science (LLHS) offers new analytical strategies specifically tailored for Heritage Science applications based on the use of laser methods. It includes techniques and systems for non-invasive analysis and advanced laser cleaning methodologies. Capabilities include expert knowledge based on almost two decades of research activity by the team, and in-house developed equipment for:
Important progress has been made in these past years both in the real-time observation of fast photoinduced chemical reactions and in the subject of intense laser control of reaction dynamics.
