Physics and applied optics

The "Laboratoire d’optique appliquée (LOA)" is a joint research unit of the CNRS, École Polytechnique, and ENSTA that has been a pioneer in laser-matter interaction and plasma physics for over 30 years.

The laboratory's research activities cover a wide range of topics in ultrafast science, including the development of ultra-intense femtosecond (10-15 seconds) laser systems, the physics of laser filamentation in air, and the creation of compact sources of radiation and energetic particles for academic, societal, and industrial applications.

The LOA is continuing to develop the LAPLACE project, a center dedicated to laser-plasma accelerators.

Chaos in Caracas : the role of sediments

During the double earthquake that struck Venezuela on June 24, 2026, damage extended as far as Caracas, the capital, more than 150 km from the epicenter. How can such extensive damage be explained at such a great distance? Jean-François Semblat, a...
