Located in Saclay, France, LIDYL is a fundamental research laboratory whose activities focus on radiation-matter interaction and applications. LIDYL's research programs cover both electronic and nuclear dynamics, in gas and condensed phases, from the simplest atomic and molecular systems to the most complex ones (biomolecules and nano-objects) and to laser-created plasmas using high-intensity fs lasers. LIDYL hosts a large panel of laser-based experimental stations and infrastructures. The ATTOLab facility based on the 2arm CEP stabilised FAB1-10 laser (25fs, 20W@10kHz and 15W@1kHz) allows generating fs/as XUV pulses with adjustable bandwidths for ultrafast dynamics studies in the gas and solid phases. UHI100 offers ultrahigh intensity (up to 100TW, 25fs) and temporal contrast (up to 1012) laser pulses to be used for relativistic optics and plasma physics, or to generate ultrashort charged particle beams for multidisciplinary studies from materials to life sciences. Other, advanced laser-based set-ups are available, including the Nanolight and Sofockle facilities, for a large variety of applications including ultrafast biophotonics, energy- and charge-transfer studies in the liquid phase, strong field physics in semiconductors and dielectrics, high-order harmonic generation in crystals, ultrafast nanoplasmonic and nanoscale imaging, femtochemistry, laser-solid interaction at high power and energy density. Based on a longstanding in-house expertise, complex characterization tools and diagnostics have been developed and are made available to the external users of LIDYL’s infrastructures.


Research with short-pulse (femtosecond/attosecond) and high-intensity/high-contrast lasers: particle acceleration, harmonic spectroscopy, XUV coherent diffraction imaging, laser-solid interaction at high intensity, organic femtochemistry. Development of ultrafast lasers and diagnostics is also an area of excellence.
