被引用回数：10 パーセンタイル：45.46(Optics)The relativistic Vlasov equation is integrated numerically in order to investigate the phase space development of the wave break of a relativistic Langmuir wave in a thermal plasma. Relativistic effects lead to a differential retardation in the time required by the electrons to evolve in phase space, the largest momentum electron staking the longest time. This leads to the formation of long lasting spikes in momentum space at the wave break position that propagates with a velocity close to the speed of light and to extremely steep density jumps in coordinate space.

被引用回数：79 パーセンタイル：90.15(Physics, Multidisciplinary)Experimental evidence of plasma jets ejected from the rear side of thin solid targets irradiated by ultra-intense (

W cm
) laser pulses is presented. The jets, detected by transverse inter-ferometric measurements with high spatial and temporal resolutions, show collimated expansion, lasting for several hundreds of picoseconds, and have substantially steep density gradients at their periphery. The predominant role played by radiation pressure of the laser in the jet formation process is highlighted analytically and by extensive two dimensional particle in cell simulations.
