Abstract
We report on carrier relaxation dynamics close to the Dirac point in epitaxially grown graphene under pulsed excitation with 10-250 meV photons. With decreasing photon energy, we identify different regimes - induced transmission with bi- and single-exponential decay as well as induced absorption - and discuss their physical origin.
