Abstract

The model of evaporation, motion and compression of shell laser targets in low-entropy regime is considered. The evaporation rate and accelerating pressure in spherical targets are determined in the stationary corona model. The scaling relation are obtained which make it possible to correlate laser pulse and target parameters and optimize target compression and heating for various values of laser pulse wavelengths and energy. The results of this model are compared with numerical calculation of hydrodynamic and thermal conductivity equations.
