We demonstrate the generation of half-cycle terahertz pulses with elliptical polarization and 167 nJ pulse energy. These pulses have been generated using a 6H-SiC Large Aperture Photo-conductive Antenna (LAPCA) covered with a binary phase mask and ex

Les processus dynamiques se produisant lors de transitions de phase ultra-rapide peuvent etre deduits a partir de mesures de diffraction ou d'absorption de rayonnement X. Les lasers femtosecondes ont recemment ete utilises pour etudier la dynamiques

We study transient atomic and plasma processes in the new parameter regime of hot dense matter, produced by an intense ultrashort laser pulse. Speci"cally, we study the e!ects of extremely high "elds on ion electronic structure. These high "elds are

The spectrum of tantalum emitted by a subpicosecond laser-created plasma, was recorded in the regions of the $3d\ensuremath{-}5f,$ $3d\ensuremath{-}4f,$ and $3d\ensuremath{-}4p$ transitions. The main difference with a nanosecond laser-created plasma

The efficiency of the conversion from laser energy into aluminium K-shell line energy has been measured for different interaction regimes of a sub-picosecond laser pulse with controlled preformed plasmas. We compare the cases of thermal plasmas for w

Time- and space-resolved extreme ultraviolet spectra of carbon plasmas, created with 100-fs laser pulses, are obtained with the novel technique of picosecond jitter-free streak-camera averaging. Spectroscopic diagnostics indicate electron densities a

The experimental work presented in this paper focuses on the consequences of both nonlocal heat transport and rapid time variation in atomic physics as a function of the initial gradient scale length of a plasma. We look at the time history of K-shel

Ultrafast x‐ray techniques can, in principle, allow us to more directly watch the time evolution of matter, with atomic spatial resolution and with time resolution on the scale of atomic motions such as the making and breaking of chemical bonds, in

We present some recent results on the temporal evolution of X-ray images and spectra of laser produced plasmas. These results illustrate our progress in the development of a new technology for subpicosecond cinematography. We discuss the perspectives
