| Popis: | We use a wide-range model of thermodynamic, transport and optical properties for simulation of laser-induced dynamics of aluminum plasma. The model describes the laser energy absorption, electron thermal conductivity and two-temperature effects of electron-ion collisions as well as hydrodynamic motion of matter. The model successfully describes experiments on self-reflectivity in wide range of intensities, and angular dependence of reflectivity coefficient for S- and P-polarized pulses. Thus, the model can be used for prediction of the main parameters of aluminum plasma such as temperature, density, velocity, mean charge of ions for optimization of planned experiments. |
