    Photoionization of highly excited atomic sodium involving core-excited resonances

    Resonant photoionization in thenl outer-shell of 2p 6 nl excited sodium is studied between 32.50 and 33.50 eV. Resonances are of the type 2p 6 nl → 2p 5 3snl → 2p 6 ελ, i.e. corresponding to the excitation of a 2

    Nonadiabatic heating of a plasma produced by the ionization of a gas by a short intense laser pulse

    A hydrodynamic model of the interaction of a short, intense laser pulse with moderate-density gases is constructed. The model systematically takes into account both tunneling-ionization processes and the relat...

    The role of the prepulse in cluster heating by a high-power femtosecond laser pulse

    The interaction of a 60-fs laser pulse with argon clusters was experimentally studied. It is shown that cluster heating by an intense femtosecond pulse preceded by a picosecond prepulse can produce plasma whos...

    The generation of fast particles in plasmas created by laser pulses with different wavelengths

    By means of spatially resolved high-resolution X-ray spectroscopy, we have investigated the generation of fast ions at various laser installations with different flux densities and laser wavelengths. It is dem...

    On the interaction of femtosecond laser pulses with cluster targets

    The heating of clusters by femtosecond laser pulses is studied theoretically and experimentally. Both the formation of a cluster target and the results of experimental studies of the cluster plasma by the meth...

    X-ray spectroscopy diagnostic of a plasma produced by femtosecond laser pulses irradiating a cluster target

    The parameters of a plasma produced upon the interaction of ultrashort laser pulses with cluster targets are measured by the methods of X-ray spectroscopy. The dependence of the plasma parameters on the initia...

    High order harmonic generation by non-linear reflection of a pedestal-free intense laser pulse on a plasma

    We demonstrate the influence of the prepulses and ASE of ultrashort pulses interacting with a solid target by addressing the direct comparison of the harmonic spectra generated by reflection onto a solid targe...

    Plasma mirrors for ultrahigh-intensity optics

    Specular reflection is one of the most fundamental processes of optics. At moderate light intensities generated by conventional light sources this process is well understood. But at those capable of being prod...

    X-ray spectroscopic diagnostics of ultrashort laser-cluster interaction at the stage of the nonadiabatic scattering of clusters

    X-ray spectroscopic diagnostics of laser-cluster interaction at the stage of nonadiabatic scattering of clusters and formation of a spatially uniform plasma channel has been performed. The experimental investi...

    Ion acceleration in ultra-high contrast regime

    In this work, we demonstrate that the contrast of high intensity laser pulses is a key issue for many problems dealing with high-field interaction with solid-density matter. As an example, we will discuss the ...

    Effect of low-level laser therapy on the gene expression of collagen and vascular endothelial growth factor in a culture of fibroblast cells in mice

    Low-level laser therapy treatment (LLLT) is widely used in rehabilitation clinics with the aim of accelerating the process of tissue repair; however, the molecular bases of the effect of LLLT have not been ful...

    FAB10: a user-oriented bandwidth-tunable extreme ultraviolet lightsource for investigations of femtosecond to attosecond dynamics in gas and condensed phases

    We present the commissioning of the FAB10 beamline (Femtosecond to Attosecond Beamline at 10 kHz repetition rate) that has been developped and operated in the last few years at the ATTOLab facility of Paris-Sa...
