Understanding cosmic ray generation in the lab
By combining high-power lasers and intense magnetic fields, researchers succeeded for the first time in demonstrating particle acceleration during the interaction of a collisionless shock wave with a magnetized ambient medium.

Unusual nucleic acid structures
More than 60 years after the discovery of the double helix, we have yet to grasp the structural complexity of nucleic acids. These biomolecules cannot be viewed as simple single- or double-stranded linear polymers, but rather as complex 3D architectures. We are interested in two non-canonical confo…

Victor Lafaurie defended his PhD "Pulsed plasma approach for mild or strong ignition of a detonation wave using gradient of atomic species"
On March, 2025, Victor Lafaurie defended his PhD "Pulsed plasma approach for mild or strong ignition of a detonation wave using gradient of atomic species".Abstract :This thesis presents a study conducted on the ignition of a detonation wave with non-equilibrium plasma. This form of plasma-ass…

Wave coupling in solar winds
Solar flares generate radio waves that are detected on Earth. Understanding these signals would allow to better anticipate flares and their effects. At LULI, laser-plasma interaction was able to reproduce some of these radio waves, in order to study their properties.What we have achieved at LULI :S…

Wave propagation in meta materials and dispersive media
Black-hole wave on a conical tipThis theme concerns propagative media whose physical features, which are usually represented by positive constants, become negative in some frequency ranges. This implies in particular that these media are dispersive, in the sense that their physical features depend …

WAVES 2022: 15th International Conférence on Mathematical and Numerical Aspects on Wave Propagation
WAVES 2022: Une rencontre humaine et scientifique pour célébrer un double anniversaire
L’édition 2022 de la conférence WAVES est organisée à l’ENSTA Paris à Palaiseau (à 20km au sud de Paris). La toute première édition de la conférence, qui s’est tenue à Strasbourg en 1991, a été initiée par des…

X-ray lasing in the keV range
A new method to generate ultra-short x-ray laser pulses, lying on a laser-driven betatron source of photo-pump inner-shell transitions, was proposed. ISPI has been the subject of several theoretical and numerical studies since its “discovery” in 1967 but no experimental demonstration has been achie…

XCAN
Coherent Laser CombinationCoherent Beam Combination (CBC) can be seen as the spatial counterpart of Chirp Pulse Amplification (CPA). Indeed, when CPA distributes energy temporally to lower the peak power before amplification, CBC distributes energy spatially for the same purpose. The concept is ill…
