Plasmonic-assisted laser harmonics in crystals
The PACHA project aims to explain the electronic mechanisms involved in the generation of high-order harmonics in crystals. In addition, with the aim of using this radiation for experimental applications (because of its spatio-temporal properties -short duration, spatial coherence, short wavelength- harmonic radiation is very interesting for multiple fundamental and applied applications), the project explores different strategies for locally increasing laser intensities.This way, more compact and less complex laser systems can be used. Two distinct avenues are being explored: coupling laser pulses with resonant plasmonic structures and guiding pulses in dielectric structures.
Partners :
The PACHA project is a single-partner ANR JCJC-type project led by Willem Boutu of LIDYL.
It has nevertheless benefited from the support of numerous partners in France (CEA/SPEC, ISMO, IOGS, XLIM) and abroad (ICFO – Spain, Leibniz Universität Hannover – Germany)
This project has received funding from the Agence Nationale de la Recherche program under convention ANR-17-CE30-0008-01.
