Abstract

We report on the computer simulation results for a new laser plasma interaction regime, concentrating on the collisionless, kinetic nature of the plasma motion. It is found that even for normal incidence, the absorption of the laser light by the plasma electrons near critical can be as high as 60%, and that the temperature of the hot electrons produced can be predicted simply by knowing the associated ponderomotive potential of the incident laser. We also describe a new odd harmonic generation mechanism due to the interaction of the laser with the plasma electrons near critical.
