Paper Abstract

Effects of laser polarization were studied on behaviors of fast electrons produced from an aluminum target irradiated by obliquely incident laser pulses at 8x1015 W/cm2. Jet emission of outgoing fast electrons collimated in the polarization direction was observed for the s-polarized laser irradiation, whereas for the p-polarized irradiation, very directional emission of outgoing fast electrons was found close to the normal direction of the target. The behaviors of in-going fast electrons into the target for s- and p-polarized irradiation were also investigated by observing x-ray Bremsstrahlung radiation at the backside of the target.
