We present a Monte Carlo simulation of ultrafast absorption saturation studies of hot carriers in GaAs. We show that carrier-carrier scattering is the dominant scattering mechanism in the femtosecond time regime and that pump and probe experiments are the ideal tool for the study of the strength of this interaction. Three different approaches are used to study carrier-carrier scattering and the best agreement with experimental results is obtained by molecular dynamics.
