Photosciences: Light plays a role in many physical and chemical processes; it is also an exceptional tool in the investigation of matter. Photo-scientists within laboratories of IRAMIS study the interaction between light and matter as a fundamental process and an analysis tool.
Lasers: Photoscience is becoming increasingly important due to the rise of ultra-short light pulses, often ultra-intense. New particles and radiation sources, with exceptional properties, can be obtained via laser-matter interactions.
Plasmas: Understanding the properties of dense and hot plasmas is important for CEA. Lasers make it possible to create and probe plasmas.
