Abstract :
Summary form only given. We present a study of carrier relaxation in bulk GaAs at room temperature in the quantum kinetics regime. We use a modified frequency-resolved pump-probe technique with pump and probe durations independently adjustable from 30-100 fs. Differential absorption spectra (DAS) for 70-fs pump and probe at low excess energy is presented.
