Since January 2015, the Aimé Cotton Laboratory has been run as a joint research unit by CNRS, Université Paris-Sud and ENS Paris-Saclay.
The laboratory is headed by Jean-François Roch, with Djamel Benredjem as deputy director.
The laboratory has three sections:
- Atoms, light & applications
- Cold matter: interactions, correlations and complexity
- Photons, materials and interfaces
Among its long-term research themes is the spectroscopy of ions in crystals.
This subject has been studied continuously in the laboratory in view of developing solid new laser sources and, more recently, of designing quantum memories and enabling the spectral analysis of radiofrequency signals.
