Atomic process in plasmas produced by a ultrashort pulse laser

In plasmas produced by an intense ultrashort pulse laser, the plasma density is almost solid density and the temperature is lower than 100 eV. Since the ions are strongly coupled for such plasmas, the ion-ion correlation is important to be described by the hypernetted-chain (HNC) equation. On the other hand, the electron-ion correlation can be described by the linear response theory. By using those correlation functions, evaluated are the ion potentials. The behaviors of the free and bound electron in the strong laser field are investigated by the Schroedinger equation which is transformed to the Kramers-Henneberger (KH) frame. As the results, the ionization rate and harmonics generation are evaluated. (author). 8 refs, 2 figs
