被引用回数:21 パーセンタイル:63.98(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:81.84(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:5 パーセンタイル:36.71(Physics, Multidisciplinary)X-ray spectroscopy diagnostics of laser-cluster interactions at a stage of non-adiabatical cluster expansion and formation of the spatially homogeneous plasma channel is carried out for the first time. It is shown, that X-ray line emission spectra of light elements, allows to determine parameters of the plasma formed at the time moment 10 ps from the beginning of femtosecond laser with relatively high plasma temperature Te 100 eV iand electron density Ne about 10 - 10
