Attosecond Science
Spectroscopy has taught us how the very precise measurement of resonance lineshapes gives insight into the structure of matter. However, as a time-integrated measurement, the spectral lines give only indirect information on the underlying electronic dynamics.

EUV metrology and lens-free imaging
Nanolite is a collaboration and joint laboratory between LIDYL and Imagine Optic, launched in 2020. This platform is dedicated to the development of new optical metrology methodologies and imaging at short wavelengths, particularly in the extreme ultraviolet spectral range (EUV, between 10 and 100 nm wavelength).
Generation of high-order harmonics in crystals
High-order laser harmonic generation (HHG) is a non-linear process in which a target is illuminated by an intense laser pulse and high harmonics of the fundamental frequency are generated. HHG in solids was first reported in 2011 and has been demonstrated in various dielectrics and semiconductors.

Molecular Imaging
Molecular imaging with a sub-femtosecond resolution is made possible by the built-in attosecond rescattering dynamics leading to single ionization and elastic rescattered photoelectron as well as double and multiple ionization from inelastic recollision.
Theory and Simulation
Numerical simulation activities aim at supporting the experiments on High-order Harmonic Generation (HHG), carried out by the Attophysics Group on the AttoLab laser facility.

Attosecond Beamlines
The ATTOphysics Group is the Coordinator of the brand new national facility ATTOLab. Initiated by an Equipment of Excellence (Equipex) program of the National Research Agency (ANR), it gathers nine laboratories representing eight institutions.
