Theoretical studies of laser light interaction and optical and X-ray emission from dense metallic plasmas
Abstract
The interaction of a high power CO2 laser with a dense plasma is investigated. Stimulated Brillouin scattering and thermal self-focusing of the incident beam is studied. The dynamics of a strongly turbulent plasma generated by laser-plasma interaction, and the behavior of nonlinear waves (solitons) in the plasma is analyzed. Advanced MHD plasma simulation models are employed to study the complex dynamics of nonequilibrium plasmas interacting with laser radiation. MHD computer codes capable of simulating exploding wire or pinch dynamics subjected to intense laser irradiation are developed. Radiation transport effects, such as X-ray line emission and re-absorption in optically thick regions of the plasma, are incorporated in the MHD computer code.
