Abstract
The energy spectra of fast electrons produced by ultrashort, high-intensity laser pulses were directly measured using a magnetic spectrometer with an imaging plate. The typical temperature was 350 keV for irradiation on 30 mu m thick copper film by pulses of width 43 fs, intensity 2.7x10(18) W/cm(2), repetition rate 10 Hz without artificial prepulses and was found to be clo se to the ponderomotive potential. In addition, the energy spectra of high- energy photons, which are expected to be produced from the electrons, were calculated. (C) 2001 American Institute of Physics.
