What the facility does

National and international users can access a variety of laser systems, ultrafast sources, and beamlines.

Areas of expertise

The Advanced Laser Light Source (ALLS) facility is located at the Varennes campus of the Institut National de la Recherche Scientifique, Centre Énergie, Matériaux, et Télécommunications, where national and international users can access a variety of laser systems, ultrafast sources, and beamlines. 

With the ALLS’s powerful lasers, the facility provides to users a large variety of light sources ranging from THz (300 micron wavelength) to hard X-rays (Angstrom – 0.1 nm wavelength), and electron beams, within ultrashort pulse durations. Since these light sources and beams are generated in an all-optical way, they are spatially and temporally synchronized. As a result, the facility opens the door to explore the potential of dynamic imaging of atomic, molecular and condensed matter systems and provides unique tools to explore the fundamental questions of physics and chemistry. This leads to important outcomes in fundamental science as well as in innovative technological applications and tools. Among these applications are high-spatial resolution material and medical imaging, micro-machining and materials processing, as well as applications for security and defence, telecommunications and information.

Finally, access to ALLS is based on scientific and innovative merit, through a well-defined process, which involves the evaluation of letters of intent (LOI) by an independent scientific/technology committee called the Beam Time Allocation Committee (BTAC). Twice a year, a call for beam time is announced defining an ALLS session and users send their LOIs to the ALLS scientific coordinator. Once the letters are received, the BTAC evaluates them. ALLS reserves a specific number of weeks per year (up to 25 percent) for projects with Canadian companies and government agencies.
