A wide-range model for simulation of pump-probe experiments with metals

Transport and optical properties of warm dense aluminum in the two-temperature regime: Ab initio calculation and semiempirical approximation

“…In the more complicated approximations the temperature growth of the effective collision frequency in the liquid phase is limited by some maximum value 5,19 . This approach is often used in the simulations of femtosecond laser heating 5,8,9 .…”

“…The usual approach to obtain transport and optical properties in the wide range of parameters is to interpolate between high-and low-temperature asymptotics 5,18,19 .…”

“…Different approaches may be used to simulate these experiments. Two-temperature hydrodynamic model 5 and combined continuum-atomistic modeling 6 are widely used.…”

“…If the whole process of the target heating and postevolution is to be studied, the full hydrodynamic simulation is necessary 5 . Two-temperature equation of state, valid in the broad region of densities and temperatures, should be available.…”

Electron acceleration at grazing incidence of a subpicosecond intense laser pulse onto a plane solid target

“…In this paper, the generation of hot electrons at grazing incidence of a subpicosecond intense laser pulse onto a plane solid target is analyzed for the parameters of the petawatt high-energy laser for heavy ion experiments (PHELIX) (Bagnoud et al, 2010;Wagner et al, 2014a) using three-dimensional (3D) particle-in-cell (PIC) modeling (Pukhov, 1999) and a wide-range hydro modeling (Povarnitsyn et al, 2012a) of the preplasma expansion under the action of the laser prepulse. Elaboration of wide-range models of the laser-matter interaction is necessary for planning and interpretation of experiments carried out in view of different applications aimed for the development of secondary sources of high energy particles and hard radiation (Morace et al, 2014;Brabetz et al, 2015;Rusby et al, 2015;Vaisseau et al, 2015).…”
