Preplasma effects on the emission directions of energetic electrons in relativistic laser–solid interactions

Journal of Plasma Physics (2006)

Y. Y.Z. M. Sheng Yutong Li Jie Zhang Xiaohui Yuan

Motivated by recent experimental observations of fast electron jets emitted along the target surface in intense laser–solid interactions with a large incident angle of the laser pulse, we simulate electron emissions by two-dimensional particle-in-cell simulations. When there is no preplasma in advance of the main laser pulse, electrons are emitted dominantly along the target surface. However, when there is preplasma, electron emission changes to the target normal. This difference originates from the different absorption mechanisms and different Coulomb electrostatic fields and self-generated magnetic fields induced in front of the target for the two cases.

Long-distance femtosecond laser filaments in air

Laser Physics (2009)

Jie Zhang X. R. Lü Y. Y.T.-T. Xi Y. T. Li

This paper reviews the recent studies of filamentation of femtosecond lasers pulses in air in the Institute of Physics, Chinese Academy of Sciences. The filamentation mechanisms of free propagated femtosecond laser pulses, effect of air turbulence on the filamentation, interaction between filaments are presented.

Demonstration of bulk acceleration of ions in ultraintense laser interactions with low-density foams

Physical Review E (2005)

Yutong Li Z. M. Sheng Y. Y.Zheng Jin Jie Zhang

Ion acceleration inside low-density foams irradiated by ultraintense laser pulses has been studied experimentally and theoretically. It is found that the ion generation is closely correlated with the suppressed hot electron transport inside the foams. Particle-in-cell simulations suggest that localized electrostatic fields with multi peaks around the surfaces of lamellar layers inside the foams are induced. These fields inhibit hot electron transport and meanwhile accelerate ions inside the foams, forming a bulk acceleration in contrast to the surface acceleration at the front and rear sides of a thin solid target.
