Laser induced plasma

When a laser radiation is focused on a sample (solid, liquid and gas), its electromagnetic energy is transformed in to electronic excitation (free electron, plasmons). If the laser energy exceeds a characteristic threshold (depending on sample features and laser parameters), evaporation, atomization, and partial ionization of the sample will result. Laser induced plasma (LIP) is defined as the generation of a totally ionized gas, a plasma, that practically is a ‘gas’ of charged particles. Therefore a short-pulse high power laser beam focused onto a sample converts a finite volume of sample instantaneously into its vapor phase constituents in an expanding plasma cloud. The high electron density and the high temperature sustain a plasma that then will rapidly evolve through a series of kinetic mechanisms. The study of the temporal and spatial evolution of LIP in different environments by the spectroscopic techniquesleads to the required knowledge useful for a wide range of application fields (i.e. chemical analysis, nanoparticles and nanostructures production).

Diagnostics of Laser Induced Plasma (LIP) processes:

Experimental studies of Laser  Induced Plasma (LIP) fundamental aspects with the following techniques:

  1. High temporally and spatially resolved Optical Emission Spectroscopy

Disordered serendipity: a glassy path to discovery

A workshop in honour of Giorgio Parisi’s 70th birthday

September 19-21, 2018 - Roma

Sapienza University

With the occasion of celebrating Giorgio Parisi 70th birthday, the conference "Disordered serendipity: a glassy path to discovery" brings to Rome many among the world-leading experts in the field of complex systems. In order to properly represent the many fields of research where Giorgio Parisi gave a relevant contribution in his studies of disordered systems, the conference covers a broad spectrum of topics: from  fundamental and rigorous analysis of the statistical mechanics of disorder systems to applications in biology and computer science. These subjects are deeply interconnected since they are characterized by the presence of glassy behavior.
