Fast electrons were produced by laser irradiation of 43-fs, 2.7X 10 18 W/cm 2 on a 30 li m thick copper target. The energy spectra of the electrons were directly measured using a magnetic spectrometer with an imaging plate. The typical temperature was 350 keV for 15°i rradiation and was found to be close to the ponderomotive potential at the intensity 2.7X 10 18 W/cm 2 . The energy spectra of high-energy photons, which are expected to be produced from the electrons, were also calculated. CP634,
