With deep sadness, we announce that our colleague and friend Bertrand Carré passed away last Tuesday, at the age of 60.

After graduating from Ecole Polytechnique, Bertrand performed his Doctoral studies at CEA-Saclay, where he then made a rich scientific career. Internationally-renown expert of laser-matter interactions, he first developed the spectroscopy of excited atoms in weak fields, and then turned to the physics of atoms and molecules in strong fields. Head of the Attophysics Group, he strongly contributed to the emergence of attosecond physics with landmark papers, e.g., on the attosecond synchronization of high order harmonics or on molecular orbital tomography.

Dedicated to serving the community, Bertrand invested strong effort in structuring the important scientific community working on ultrafast dynamics at the Paris-Saclay University. He was the architect and then the coordinator of the Equipment of Excellence ATTOLab, a state-of-the-art interdisciplinary platform inaugurated in February 2017 in a highly competitive international environment.

The colleagues who had the opportunity to meet him will remember his exceptional human qualities, always caring, helpful and supportive, his modesty as well as his incredibly broad culture. We will miss him!
