Simulations of laser plasma interaction for shock ignition in the high intensity regime
Original language description
A preassembled fuel is ignited by a strong converging shock in the shock ignition (SI) approach to inertial confinement fusion (ICF). The shock is launched by a high power laser with the intensity 1-10 PW/cm2 and the wavelength 351 nm. In this paper, itis shown that the laser pulse absorption at the higher intensity range takes place in the density cavities, which develop in plasma with density below quarter critical. The absorption reaches about 70% the energy flux into the target is due to fast electrons with the temperature 24 keV. Both of these results do not depend on the laser intensity in the domain around 10 PW/cm2. In the initial transient stage during the time of several tens of ps, the SBS reflectivity shows a series of strong spikes with intensity several times higher than the incident laser pulse intensity. These SBS spikes are so intense that they induce Raman backscattering while propagating outside the target. This Raman scattered light propagates into the target and i
