Sources de lumière extrême et métrologie optique / Extreme light sources and optical metrology
Plusieurs équipes du LIDYL contribuent au développement de sources de lumière extrême (impulsions lasers ultra intense / ultra brèves), ainsi qu'au nécessaire développement de la métrologie optique associée avec la mesure de profil d'intensité ultra-intense ou de durée d'impulsions dans le domaine attoseconde (10-18 s).
Recherche et développement laser (@ LIDYL/SLIC)
Le groupe SLIC mène des programmes de R&D visant à maintenir les plates-formes laser du LIDYL à un haut niveau de performances et à les adapter aux nouveaux besoins de leurs utilisateurs.
Physique et chimie femtoseconde-attoseconde / Femtosecond-attosecond physics and chemistry
While the pulse durations of infrared lasers are reaching the fundamental limitation imposed by the duration of the optical cycle (a few femtoseconds), High-order Harmonic Generation has recently opened a new field by accessing the attosecond regime (1as = 10-18 s). HHG spectra are made of lines corresponding to the odd multiples of the fundamental laser frequency, and can cover a very broad spectral range, from visible light to soft X-rays.
Matter under Extreme Conditions
The MEC laboratory is a fundamental research lab where two closely related topics are investigated, on the one hand the interaction of matter with a strong laser field, i.e., at high power density, on the other hand the matter at very high energy density, i.e., hot dense plasmas. The MEC lab is composed of 3 interacting research groups, namely Attophysics, Physics at High Intensity (PHI), and High Energy Density Matter (HEDM).
Photosciences: Light plays a role in many physical and chemical processes; it is also an exceptional tool in the investigation of matter. Photo-scientists within laboratories of IRAMIS study the interaction between light and matter as a fundamental process and an analysis tool. Lasers: Photoscience is becoming increasingly important due to the rise of ultra-short light pulses, often ultra-intense.
