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. 

ATTOLab provides an experimental platform for interdisciplinary studies of ultra-fast dynamics - electronic and nuclear dynamics at femtosecond (10-15) and attosecond (10-18) timescales – in systems in the gas, condensed and plasma phases.


Two state-of-the-art attosecond beamlines have been developed (for details, see ATTOLab) :

  • One attosecond beamline (SE1), is driven by the FAB1 laser (1 kHz, 15 mJ, 24 fs, CEP). The high laser energy allows multiple-beam designs as well as spatio-temporal/spectral shaping (e.g. frequency conversion using an OPA) for a versatile and flexible attosecond beamline.

  • One attosecond beamline (SE10) is driven by the FAB10 laser (10 kHz, 2 mJ, 23 fs, CEP). This brand new beamline is dedicated to high reprate applications. It includes an innovative spectro-temporal selection module developed in the frame of the OPT2X and Pulse-X projects. It allows fast switching between 3 working modes ranging from ‘narrow band/10fs’ to ‘very broad band/100as’ operation.
