摘　　要：Hot electron spectrum and angular distribution generated from the interaction of ultra-short pulse laser (744 nm/120 fs/12 mJ) with solid (Cu) plasma target have been studied experimentally whichHot electron spectrum and angular distribution generated from the interaction of ultra-short pulse laser （744 nm/120 fs/12 mJ） with solid （Cu） plasma target have been studied experimentally which have been measured utilizing electron-magnetic meter and imaging plate （IP）. And the angular distribution was measured in the incidence plan. At the condition of pre-pulse free and P polarization and 45° incidence, the temperature of hot electron fitted by Maxwellian is 56 keV, and the hot electrons are emitted mainly along the normal of targets. The dominant mechanism of hot electron generation is vacuum heating. The charge separation potential is about 70 keV.
