Abstract First measurements of relativistic electrons produced by the interaction between a 400-fs, 1.06-{mu}m ultrahigh-intensity laser pulse ({ital I}{approx_gt}10{sup 19} W/cm{sup 2}) and a solid target are presented. For electrons ejected along the laser propagation axis in the forward direction, the relation of the hot temperature {ital T}{sub {ital h}} versus the laser intensity {ital I} is found to be in very good agreement with a {ital J}{times}{ital B} ponderomotive model described by S.C. Wilks {ital et} {ital al}. [Phys.Rev.Lett.{bold 69}, 1383 (1992)], where {ital T}{sub {ital h}}=({gamma}{sub osc}{minus}1){ital mc}{sup 2}. Hot temperature of transverse electrons scales as {ital T}{sub {ital h}}{approximately}{ital I}{sup 1/3}. {copyright} {ital 1996 The American Physical Society.}
