Pre-plasma effect on laser beam energy transfer to a dense target under conditions relevant to shock ignition
Original language description
Paper reports on properties of a plasma formed by sequential action of two laser beams on a flat target, simulating the conditions of shock-ignited inertial confinement fusion target exposure. The experiments were performed using planar targets consisting of a massive copper (Cu) plate coated with a thin plastic (CH) layer, which was irradiated by the 1? PALS laser beam at the energy of 250 J. To study the parameters of the plasma treated by the two-beam irradiation of the targets, a set of various diagnostics was applied. The 2D numerical simulations have been used to support the interpretation of experimental data. The general conclusion is that the fraction of the main laser beam energy deposited into the massive copper at two beam irradiation decreases in comparison with the case of pre-plasma. The efficiency of the energy transfer from the main laser pulse to a solid part of targets is deteriorated by means of the fast electrons and the wave of an electron thermal conductivity.
