IRAMIS "Saclay Institute of Matter and Radiation" is the 2nd Institute in size of the CEA Fundamental research Division (DRF). IRAMIS gathers 6 joint Research Units in association with CNRS, Ecole Polytechnique or ENSICAEN. Four are located on the CEA Research Centre of Saclay (LIDyL, LLB, NIMBE and SPEC), one on the site of the Ecole Polytechnique (LSI) and one in Caen (CIMAP), close to GANIL.
Mostly fundamental, the research in physics and chemistry carried out at the Institute are in close connection with societal issues and CEA programs :
Mostly fundamental , research carried out at the Institute are open to the creation of economic value and technology transfer. IRAMIS also contributes to 4 EQUIPEX and 4 LABEX of the "Investments for the Future" programmes of the French government.
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.
In the last two decades, new superconducting (SC) compounds, exhibiting surprisingly high critical temperatures (Tc), have been discovered. In contrast to conventional superconductors, the SC order parameter is not isotropic, neither in cuprates nor in Fe-based systems. This ignited a search for new SC pairing mechanisms based on the existence of rather strong electronic interactions.
