Superhot-x-ray and -electron transport in high-intensity CO2-laser-plasma interactions
Abstract
A comprehensive investigation of the high-energy [(70-400)-keV] x-ray emission from CO2-laser-produced plasmas at intensities up to 3×1014 W/cm2 has revealed the presence of a ``superhot'' component. The intensity of this component scales very strongly with incident laser intensity. It is expected that for intensities 5×1015 W/cm2 energy balance in CO2-laser-produced plasmas would be dominated by the energetic electrons responsible for this high-energy x-ray emission.
