The Laboratoire d'Optique Appliquée (LOA) is specialized in ultrashort, and often intense, laser physics. Ultrashort, ultra-intense lasers have opened many new pathways to investigate laser-matter interactions. In this domain, LOA installations are unique in Europe in terms of performance. One ultra-high intensity laser produces at least 10**20 W/cm 2 at the focus (100 TW, 25 fs pulses), the world highest intensity at 10 Hz, thus opening up totally new regimes of physics. Moreover, several other cutting-edge laser systems allow users to benefit from a variety of laser specifications.
Secondary sources ranging from mid-IR to VUV and laser-based X-ray sources also allow time-resolved experiments with femtosecond accuracy. Research topics include: high-intensity laser-matter interaction, superdense plasmas, relativistic electron acceleration, generation of intense bursts of X-ray radiation for time-resolved diffraction studies, generation of high-order harmonics, self-guided propagation of intense femtosecond pulses as well as solid state physics and biochemistry at ultrashort timescales. LOA is partner in a cluster (LIMANS 3) of 7 laser Research Infrastructures: MBI (Berlin, Germany), LLC (Lund, Sweden), FORTH (Heraklion, Greece), LENS (Florence, Italy) and LCVU (Amsterdam, Netherlands), and since a few months CUSBO (Milano).
Interested researchers are advised to get in touch with the Facility technical manager (firstname.lastname@example.org) to get information. The web site http://wwwy.ensta.fr/loa-facility gives all practical instructions on the preparation of a research project. The final application takes place electronically at: http://limans3.mbi-berlin.de. Selection is performed by an independent international committee, common to all LIMANS 3 laser facilities.
