Abstract

This paper reports hot electron energy spectrum measured with electron spectrometer, and Optical Transition Radiation measured with optical timeintegrated image of CCD during the interaction of lasersolid target in targets at the rearside radiation of laser on 20 Terawatt femtosecond laser facility. It shows that hot electron energy spectrum can be fitted with twotemperature likeMaxwellian distribution, with T≈90 and 280 keV,but average temperature of hot electrons T≈185 keV, which accorded with the known temperature scaling law. Because Optical Transition Radiation is produced by the hot electrons transport through solid targets, region of Optical Transition Radiation has lager radiation angle and optical intensity distribution. The main acceleration of hot electron comes from resonance absorption.
