Simulations of spectra from dense gold laser-produced plasmas

Using the detailed configuration accounting with the term structure treated by the unresolved transition array model, the authors calculate the M band 5f-3d transmission spectra of hot dense plasma in local thermodynamic equilibrium, which is produced by high-power laser. The authors can study the ion charge stage and ionic fractional population and spectral intensity for the Au's laser plasma. The authors not only can judge the temperature and density of the laser plasma, but also can offer the important physical parameters, such as ion stage and population distribution. It is feasible to simulate the average ionized stage and charge state distribution in a well characterize highly ionized Au Plasma. (authors)
