Laser-Produced Plasmas and Radiation Sources.

Abstract

An experimental and theoretical study of CO2 Laser-induced gas breakdown, laser heating of magnetically confined plasma, and emission of soft X-rays from laser-heated plasma has been performed. Demonstrations were made of the roles of electron diffusion, pulse time, and inelastic losses in laser-induced gas breakdown. The phenomenon of CO2 laser beam self-trapping and associated plasma dynamics were studied. High-Z plasma impurities and magnetic field were shown to increase the heating and soft X-ray emission from CO2 laser-heated plasmas.
