Gasdynamic processes in heating of a substance by laser radiation

Nuclear fusion by laser radiation

“…Two theoretical approaches have been made [15,16] and [17] which differ by the assumption made on the absorbing layer.…”

“…When self-similar solutions are used [15,16], one must assume that the laser light is absorbed in a large volume where the average density p is much smaller than the cut-off value p c . In this case, the optical thickness of the heated matter remains constant and nearly equal to 1.…”

“…In this case, the optical thickness of the heated matter remains constant and nearly equal to 1. The plasma parameters are varying with time in a self-similar way and for a constant laser flux one can derive the following scaling laws from Refs [15,16].…”

Nonlinear Electron Heat Conduction Equation and Self-Similar Method for 1-D Thermal Waves in the Laser Heating of Solid Density DT Fuel

“…The interaction of an intense laser beam with a plane solid target has been considered by a number of authors [8][9][10]. In the last decades, the dominant role of heat conduction in the early stages of laser interaction with solid targets has been widely appreciated [11][12][13][14][15][16][17].…”

Two-dimensional hydrodynamic models of laser-produced plasmas

“…Ablative models are the familiar representations of laser-produced plasmas. The self-regulating model of Afanasev et al (1966) and Caruso, Bertotti & Giupponi (1966) has been progressively developed by Nemchinov (1967), Caruso & Gratton (1968), Puell (1970) and Pert (19866) to give an accurate representation when inverse bremsstrahlung absorption is dominant and thermal conduction negligible. On the other hand, the deflagration model of Fauquignon & Floux (1970), formalized by Bobin (1971), Gitomer, Morse & Newberger (1977, Max, McKee & Mead (1980) and Pert (1988), describes the behaviour when absorption is at the critical density and thermal conduction significant.…”
