Since an imaging plate (IP) is sensitive to electron, ion, and x rays, it can be used as a detector for laser plasma experiment using ultraintense laser. Moreover, an IP has the advantageous features such as high sensitivity, wide dynamic range, and high spatial resolution. Even though IP itself has a considerable wide dynamic range up to 105, the IP data have appeared often saturated at an IP reading device. We propose a reading technique by inserting optical density filters so that an apparently saturated IP data can be saved.

    We have questioned the conventional criterion, which is the critical power for self-focusing, to predict the stopping position of a filament. Our experimental result suggests that during the filamentation process the plasma induces an additional diffraction of the laser beam. This is another...

    Near-forward scattering of laser light in a plasma, in regimes relevant to future inertial-confinement-fusion (ICF) experiments, has been investigated experimentally. The intensity scaling of stimulated Raman scattering (SRS) forward scattering at one angle was measured from a low-Z plasma. It...

    The dynamics of an electron in a finite set of linearly or circularly polarized ultra-high-intensity (above 1018 W/cm2) laser waves is investigated within the framework of a Hamiltonian analysis. The Compton harmonic resonances are identified as the source of various stochastic instabilities....
