The energy spectrum of hot electrons emitted from the interaction of a relativistically intense laser with an Al plasma is measured at a repetition rate of 0.5 kHz by accumulating approx10{sup 3} highly reproducible laser shots. In the 10{sup 17}-2x10{sup 18} W/cm{sup 2} range, the temperature of electrons escaping the plasma along the specular direction scales as (Ilambda{sup 2}){sup 0.64+}-{sup 0.05} for p-polarized pulses incident at 45 deg. This scaling is in good agreement with three-dimensional particle-in-cell simulations and a simple model that estimates the hot-electron temperature by considering the balance between the deposited laser intensity and the energy carried away by those electrons.
