Groupe APPLI (Application des sources ultrabrèves à la physique des solides)



 The APPLI group is dedicated to the development of new femtosecond particle and radiation sources and to their use for probing ultrafast dynamics in solids. We put a special emphasis on developing high-repetition rate and reliable sources that can truly be used for probing ultrafast phenomena at the femtosecond time scale. 

The group has two main activities:

  •  Femtosecond pump-probe spectroscopy on condensed matted using photons ranging from the visible to the far Infra-Red. We also use electrons to watch atoms move in solids via Ultrafast Electron Diffraction.
