  • Parametric instabilities in the presence of sinusoidal plasma density modulation are considered analytically and by numerical integration of the coupled mode equations. The density modulation tends to reduce temporal and spatial growth rates. If there is a linear density gradient in addition to the density modulation, the usual convective saturation exists for small modulation; however, above a certain threshold modulation, the convective saturation is replaced by absolute growth. This result is in qualitative agreement with earlier work on plasma with linear density gradient plus turbulence. (AIP)
  • The analytical solutions describing the linear stage of the intense-laser-pulse self-modulation, which results in a strong plasma wakefield excitation, are studied in terms of the paraxial approximation. The attention is focused on phase relations that were ignored in the previous studies. It is shown that the value of the phase velocity of the plasma wake wave differs from the pulse group velocity so that under some specific conditions, the relativistic factor corresponding to the phase velocity can be substantially less than that for the group velocity. This may be important for the particle acceleration in the self-modulated laser wakefield accelerator.
  • In this paper, two-photon absorption laser induced fluorescence spectroscopy is used to follow the nitrogen atom density in flowing dielectric barrier discharges fed with pure nitrogen and operating at atmospheric pressure. Two different dielectric barrier discharge regimes are investigated: the Townsend regime, which is homogeneous although operating at atmospheric pressure, and the more common filamentary regime. In both regimes, densities as high as 3x10{sup 14}/cm{sup 3} are detected. However, the N atoms kinetic formation depends on the discharge regime. The saturation level is reached more rapidly with a filamentary discharge. For a given discharge regime, the N atom density dependsmore » strongly on the energy dissipated in the plasma between the gas inlet and the measurement position, whether the energy is varied by varying the position of the measurements, the gas flow, or the dissipated power. Experiments performed in the postdischarge show that the N atom decay cannot be simply attributed to three-body recombination of atomic nitrogen with nitrogen molecules, meaning that other mechanisms such as surface recombination or gas impurities play a role.« less
  • We investigate the mechanism of the onset of a periodic structure in the vicinity of the critical surface of a laser plasma as a result of parametric excitation of trapped standing electromagnetic oscillations that are radiated into the region of the rarefied plasma.
