摘要：

Laser absorption, and hot electron emission and its energy spectrum are studied in the interaction between P-polarized femtosecond laser pulses at 8 x 10(15) W/cm(2) and solid-density plasmas. Comparison is made between the different behaviours of metallic and dielectric slabs irradiated by femtosecond laser pulses. It appears that there are less laser absorption, fewer hot electrons and higher hot electron temperature from dielectric slabs compared with metallic ones. These are concluded to be due to the lower conductivity and consequently lower charge separation potential of the dielectric slabs.
