Mathematical modeling of experiments on the interaction of a high-power ultraviolet laser pulse with condensed targets

Objectives . The paper aimed to review and analyze the results of works devoted numerical modeling experiments on interaction high-power ultraviolet (UV) laser pulses with condensed targets. were carried out at GARPUN, powerful KrF-laser facility P.N. Lebedev Physical Institute Russian Academy Sciences (Moscow). relevance research is related use excimer UV lasers as a driver for thermonuclear reactor. aspects laser-plasma interaction, including those possibility using two-sided cone target in fission-fusion reactor, are discussed. Methods based physico-mathematical models, Euler Lagrange. Results mathematical three types natural presented: (1) burning through different thicknesses Al foils by laser; (2) studying hydrodynamic instability development acceleration thin polymer films features turbulent zone formation; (3) two-layer targets (Al + Plexiglas) study fine structures. Numerical showed that hybrid reactor can form counter cones. Conclusions Physico-mathematical models developed along 2D codes Lagrangian Eulerian coordinates confirmed experiments. be used describe physics interacting various forecast reactor-scale
