被引用回数：21 パーセンタイル：64.71(Physics, Fluids & Plasmas)The experimental evidence of the correlation between the initial electron density of the plasma and electromagnetic soliton excitation at the wake of an intense and short laser pulse is presented. The spatial distribution of the solitons, together with their late time evolution into post-solitons, is found to be dependent upon the background plasma parameters, in agreement with published analytical and numerical findings. The measured temporal evolution and electrostatic field distribution of the structures are consistent with their late time evolution and the occurrence of multiple merging of neighboring post-solitons.

被引用回数：39 パーセンタイル：82.15(Physics, Multidisciplinary)Slowly evolving, regularly spaced patterns have been observed in proton projection images of plasma channels drilled by intense laser pulses propagating in an ionized gas jet. The analysis suggests the formation of rows of magnetized soliton remnants, with a quasistatic magnetic field associated with vortex like electron currents resembling those of magnetic vortices.

被引用回数：144 パーセンタイル：95.66(Physics, Multidisciplinary)The propagation in a rarefied plasma of collisionless shock-waves and ion-acoustic solitons, excited following the interaction of a long and intense laser pulse with solid targets, has been investigated via proton probing techniques. The shocks structures and related electric field distributions were reconstructed with high spatial and temporal resolution. The experimental results were interpreted within the framework of the nonlinear wave description based on the Korteweg-de Vries-Burgers (KdV-B) equation.
