“…It is proposed to use the method of a dynamic plasma phase plate (Voronich et al, 2001) for smoothing spatial intensity distribution of heating radiation on the target. The optical transparency of a plasma layer is an essential method of a dynamic plasma phase plate, which leads to the necessity of using the low density volume-structured media (Borisenko et al, 1994(Borisenko et al, , 2008Khalenkov et al, 2006;Moreau et al, 2009;Yu et al, 2009b) Volume-structured materials are considered as different functional elements in the inertial confinement fusion (ICF) targets (Dunne et al, 1995;Gus'kov & Rosanov, 1997;Bugrov et al, 1997Bugrov et al, , 1999aBugrov et al, , 1999bNazarov et al, 1999;Cook et al, 2008;Nobile et al, 2006). First of all, smoothing of a heating inhomogeneity and production of a steady compression of the ICF targets prove to be possible applications of those materials.…”

Aerogel foil plasma: Forward scattering, back scattering, and transmission of laser radiation

et al. 2010

Experimental results obtained with "Kanal-2" facility under the study of powerful laser pulse interaction with the low density microstructure media are presented and discussed in this paper. Forward scattering, back scattering, and transmission of laser radiation by aerogel foil plasma have been investigated. The temporal, spectral, and energy characteristics of both the radiation scattering in the direction of heating radiation beam and the back scattering radiation were studied; the directional diagrams of forward and back scattering radiation were obtained for v 0 and 2v 0 frequencies. Analysis of intensity redistribution on the heating beam cross-section after passing through a polymer microstructure target was carried out.

“…Such studies have been performed in many research centers, including the Troitsk Institute for Innovation and Fusion Research, where the experiments have been carried out on the Mishen and Angara 5 facilities (see. e.g., [1][2][3][4][5][6][7][8]). In the course of long term experiments performed on the Mishen facility, 100-800 μm thick plane targets made of agar (C 12 H 18 O 9 ) n , triacetate cel lulose (TAC) (C 11 H 16 O 8 ) n , and polystyrene foam (CH) n with mean densities in the range 1-30 mg/cm 3 were irradiated.…”

Jet structures formed during laser irradiation of porous targets with an average density of ρ = 1-30 mg/cm 3 were studied experimentally by using the diagnostic complex of the Mishen facility. To study com plicated plasma structures, the experimental data were processed using specially elaborated mathematical methods. The probability of the emergence of jet plasma structures in plane open pore triacetate cellulose targets was studied as a function of the parameter ρd, where ρ is the average mass density and d is the target thickness. Analysis of the experimental results and their comparison with the existing data on the jet struc tures formed during laser irradiation of solid density targets allowed the authors to reveal the characteristic features and mechanisms of the development of large scale plasma jets.
