Abstract
Solid target experiments carried out on copper targets with both p-
and s-polarized 130 fs Ti:Sapphire laser pulses at intensities of
W/cm2 indicate the presence of hot electron
jets with electron energies of 80 to over 250 keV and cone angles of
the order of 10 degrees at the higher energies with directions
dependent on the incident polarization. For comparison, studies on
an Argon cluster jet targets with 50 fs duration Ti:Sapphire laser
pulses at vacuum intensity of 1017 W/cm2 indicated no
detectable hot electron jet emission with electron energies above 50
keV. A 2D PIC simulation of the p-polarized solid target interaction
predicts features similar to those observed experimentally.
