Laboratoire d’Optique Appliquée (LOA) is a major laser infrastructure conducting research with a broad spectrum in ultrafast laser-plasma science. It includes the development of intense femtosecond laser sources, the study of laser-matter interaction and plasma physics, the production of compact sources of ultrafast energetic radiations and particles as well as the use of these sources for societal, academic and industrial applications. LOA belongs to three institutions: Ecole Nationale Supérieure des Techniques Avancées (ENSTA-IP Paris), Ecole Polytechnique-IP Paris and Centre National de la Recherche Scientifique (CNRS). On average, 85 persons worked at LOA with about 30 permanent researchers and associated. LOA has a wide network of collaborations in France, in Europe and abroad.
Excellence: LOA has been recognized for 30 years as a research centre for fundamental and applied physics in ultrafast science, with the mission to understand and reveal the properties of the matter under strong excitation and at the shortest time or space scales. To excite, control and probe at the highest resolution, teams have developed researches in non-linear ultrafast optics and laser-plasma physics with a long-standing tradition to perform applications in other academic fields as well as in addressing key societal issues. Quality of the research in the laboratory is based on highly competitive teams, with scientists being among the international leaders of their field. They have a clear understanding of key technical and scientific challenges that may be addressed in these fast-evolving topics: femtosecond intense laser systems, laser-plasma accelerators, laser plasma x-ray sources, laser-plasma filaments, space & time ultra high-resolution imaging with laser-plasma based sources, societal applications of laser-plasmas (radiobiology at high dose, non-destructive testing, medical x-ray imaging, laser-plasma filaments technology).
