| 摘 要： | The effects of atomic number Z on the energy distribution of hot electrons generated by the interaction of 60fs, 130mJ, 800nm, and 7×10^17W/cm^2 laser pulses with metallic targets have been studied experimentally. The results show that the number and the effective temperature of hot electrons increase with the atomic number Z of metallic targets, and the temperature of hot electrons are in the range of 190-230keV, which is consistent with a scaling law of hot electrons temperature.

| Abstract: | The effects of atomic number Z on the energy distribution of hot electronsgenerated by the interaction of 60fs, 130mJ, 800nm, and 7ti10sj{17}W/cmsj{2}laser pulses with metallic targets have been studied experimentally. The resultsshow that the number and the effective temperature of hot electrons increase withthe atomic number Z of metallic targets, and the temperature of hot electrons arein the range of 190--230keV, which is consistent with a scaling law of hotelectrons temperature. |
