Abstract
We investigate the reflection near the reststrahlen band of the optical pho non in bulk GaAs in the time domain, using time-resolved terahertz spectros copy. We find that the dynamics of the reflection measured for GaAs differs strongly from the reflection dynamics that would be expected for a TO phon on with a frequency-independent dephasing time.
