Kansai Institute for Photon Science　| 【on-site】The 119th KPSI Seminar｜High-power laser science at the Advanced Laser Light Source (ALLS)

Professor   François Légaré 

Director, Énergie Matériaux Télécommunications Research Centre

CEO, Advanced Laser Light Source (ALLS)

Abstract

The Advanced Laser Light Source (ALLS) is a unique user facility located at INRS-EMT (Varennes, Canada) counting on 40M CDN$ of investment since 2002. Since 2019, this facility has joined the LaserNetUS network and is now funded as a national research infrastructure by the Canada Foundation for Innovation – Major Science Initiatives. These fundings ease access to the facility for academic and government users. In the first part of my talk, I will give an overview of the facility’s capabilities including the most powerful laser in Canada with 750 TW. In the second part, I will discuss recent results on electron acceleration under tight focusing [1] and for high dose-rate of MeV electron beam from ambient air [2], as well as a high flux neutron beamline based on laser wakefield acceleration of electrons [3].
