L'équipe SLIC (Supports et Lasers à Impulsions Courtes) est un groupe de développement laser et de support technique. La mission principale de SLIC est de fournir des lasers de pointe pour les utilisateurs internes (LIDYL) et externes (nationaux et internationaux).

Le groupe SLIC est ainsi en charge du fonctionnement, de l'optimisation et de l'évolution des installations lasers LUCA, UHI100 et ATTOALAB / FAB1-10 du LIDYL et mène également des programmes de recherche et développement visant principalement à améliorer ces installations laser en termes de performances et de caractérisation selon l'évolution des besoins de leurs utilisateurs.

Une grande partie de la R & D est réalisée en collaboration avec la société Amplitude-Technologies au sein du laboratoire commun IMPULSE. Dans une moindre mesure, le groupe SLIC mène également des activités de RD prospective dans des domaines qui ne sont pas directement liés aux lasers LIDYL mais reposent sur des techniques liées aux lasers femtosecondes, comme l'utilisation de la technique d'amplification CPA dans les LEL XUV.

En outre, le groupe SLIC comprend les ateliers de mécanique et d'électronique, le bureau d'études mécaniques et le support informatique (webmaster et assistance aux utilisateurs). Ce support technique est essentiel au succès des activités expérimentales du LIDYL.

The SLIC team (French acronym for Supports and Short Pulse Lasers) is a group of laser development and technical support. The main mission of the SLIC team is to provide state-of-the-art lasers for internal (LIDYL) and external (national and international) users.


The SLIC group is thus in charge of the operation, optimization and evolution of the LUCA, UHI100 and ATTOALAB / FAB1-10 laser facilities of the LIDYL and also conducts research and development programs mostly aimed at improving these laser facilities in terms of performances and characterisation according to the evolution of the needs of their users.


A large part of the R&D is carried out in collaboration with the Amplitude-Technologies Company within the IMPULSE joint laboratory. To a lesser extent, the SLIC group also conducts prospective R & D in areas not directly related to the LIDYL lasers but relying on techniques related to femtosecond lasers such as the use of the CPA amplification scheme in XUV LELs.


In addition, the SLIC group includes the mechanical and electronics workshops, the mechanical design office and the IT support (webmaster and user assistance). This technical support is essential to the success of the LIDYL experimental activities.

Brief introduction to ion acceleration : Undoubtedly, the acceleration of charged particles has been one of the most active research fields in the physics of laser-matter interaction all along the last ten years. In itself, laser driven ion acceleration was already a well known phenomenon although essentially circumscribed to the thermal expansion of the coronal plasma typical of nano and sub-nanosecond low intensities laser pulses interaction regimes.
Imaging XUV interferometer : Internal conversion frequency imaging interferometer at 32nm   Interferometry allows for getting electronic density information in 2D. For this purpose, we have set up, in collaboration with Attophysic group and LCF-IO, an innovative instrument based on the mutual coherence properties of two High order Harmonic (HHG) from gas jet in the XUV domain. Interferometry, in this wavelength domain, exhibits strong difficulties, due to handling of the beams.

Perspectives : Next steps in research on laser driven ion acceleration in Saclay Relying on a rich set of human resources, technical expertise and equipment, we are going to implement an ambitious program of research. a) Energy scaling laws Most of the existing models wich are supposed to give scaling laws about  proton beams main features (maximum energy, number of accelerated particles) seem better suited to high-energy and "long" duration (~ ps) laser pulses.

Reflectivity measurement in the XUV domain : Spectrally and temporally resolved reflectivity measurement for studying the temporal evolution of a dense plasma of interest for the Warm Dense Matter problematic... The properties of Warm Dense Matter ( WDM - solid density and temperature of several eV's ) are a subject of strong interest among a wide scientist community ranging from astrophysicists to solid-state physicists.
Transmission measurement in the XUV domain : Temporal evolution of XUV transmission with 100fs resolution for characterizing plasmas created by intense irradiation of thin polypropylene foils.    The plasma is created by intense irradiation (I≈3x1017W/cm2) of thin polypropylene foils, on UHI10 laser facility (CEA-Saclay). The pedestal, which could damages the target before the arrival of the intense part of the laser pulse, has been reduced implementing plasma mirror on the laser system.
