中文摘要	The generation of gamma ray emission from interaction between femtosecond lasers and solid targets has been investigated experimentally. Apparent effects of a prepulse on gamma ray emission are observed using 150 fs laser pulses at an irradiance of I lambda(2) similar to 5x10(15) Wcm(-2)mu m(-2) focused on solid targets. The fraction of high energy photons (>100 keV) are found to be greatly enhanced by introducing a 8% prepulse at 70 picosecond before the main pulse. Measurements show that a hot electron temperature as high as 83 keV has been produced at such a modest irradiance.
