Professor François Légaré, an expert in ultrafast laser science and technology at the Institut national de la recherche scientifique (INRS), has been elected Fellow of the American Physics Society (APS) by its Council of Representatives.

Professor Légaré’s groundbreaking research in the development and application of new optical approaches to matter imaging has been widely publicized in recent years. The researcher, who directs the Advanced Laser Light Source Laboratory, has had his findings published in prestigious scientific journals such as Nature Photonics and Science.

“I am particularly honored to receive this nomination. It is a recognition of the work done by my team and my collaborators since I joined INRS in 2006.”

The professor notes that his research relies on a strong team and constant collaborators.

“It is these discussions with those around me that have allowed me to get this far in my work. I would like to thank all those who have worked with me. Science is an extraordinary human adventure.”

An important contribution to science

He will be awarded a certificate for his major contributions to the field of ultrafast science, including time-resolved coulombic explosion imaging of molecular dynamics, the development of high-power infrared lasers for soft X-ray pulse generation and applications, and the development of new approaches for the generation, amplification and characterization of ultra-short pulses.

Professor Légaré is also one of the members of the Centre Énergie Matériaux Télécommunications who initiated a partnership with LaserNetUS, a network set up and funded by the Office of Fusion Energy Sciences (FES) of the U.S. Department of Energy.

Through this collaboration, the ALLS Laboratory is able to increase the number of external users from Canada and abroad. The training of high-level personnel is essential for the new Fellow.

Congratulations Professor Légaré!
