Lasers for nuclear technologies

Abstract

International audienceA wide spectrum of laser applications for nuclear technologies and industry on the basis of the latest RandD in CEA (France) will be presented. In particular, the problems of paint and metal decontamination, tokamak plasma facing walls detritiation, remote characterisation and testing (radiometry and thermography, laser induced breakdown spectroscopy, plasma diagnostics) will be discussed. The experiments were made along with the fundamental studies on laser beam/matter interaction (laser ablation with ns, ps, fs and double-pulses) and the modelling of these processes. Other laser applications (art and cultural heritage, Mars curiosity mission, optical elements, micro-fabrication, additive manufacturing) will be under discussion as well
