LIF-ENSTA-X (LIF) is part of LOA, which is a Research Institute belonging to both "Ecole Polytechnique" and "ENSTA", two Engineering schools among the most prestigious in France. LIF has been selected in 1992 as an European Facility. LIF has a permanent staff of administrative, technical and research officers which conduct their own
research and assist European Visitors. Fifteen teams from 10 different European countries are currently performing experiments at LIF which is also a center for the training of young researchers from France and the European Union, employing 23 graduate or postgraduate students. LIF activity is mainly devoted to the development Off femtosecond lasers and their applications to the study of ultrafast phenomena. A team of 12 scientists and engineers concentrates on improving constantly ultrashort laser sources to keep their performances at the leading edge of present technology. LIF has a unique collection of femtosecond laser systems ranging from low power oscillators delivering 10 fs pulses at 100MHz to ultra-high intensity oscillator-amplifier systems offering 10exp18 W/cm2 at 10 Hz, with a pulse duration of 30 femtoseconds
Research is pursued in nonlinear optics. solid state physics, ultra-high intensity laser-matter interaction, biology, biophysical chemistry and biomedical applications.
LIF is a partner of a cluster of five European laboratories including: the LENS (Italy), the ULF-FORTH (Greece), the LLC (Sweden) and the MBI (Germany)
