Abstract
The detailed term accounting (DTA) approximation for the line absorptionand the average atom (AA) model for bound-free and free-free absorptionare used to calculate the radiative opacity of high-powerlaser-produced plasmas in local thermodynamic equilibrium (LTE).The spectral resolved opacities of Al plasmas are calculatedat the temperatures and densities of 40 eV and 0.0135 g/cm3,and 58 eV and 0.02 g/cm3. Rosseland and Planck mean opacities areobtained by integrating the spectral resolved opacities withRosseland and Planck weighting functions. The results show thatthe Rosseland mean opacity is very sensitive to the detailed profile.Radiative opacities under the same plasma conditionsare also obtained by using a completely pure AA model. Theresults from the DTA and pure AA models are then compared.
