Abstract

The reflection dynamics of a subpicosecond optical pulse was investigated under the Brewster angle of incidence at the exciton resonance in the layered compounds GaSe. The reflected pulse has a tail of a few picosecond which allows the decay of the resonant polarization. A time oscillatory decay of the transient reflectivity was observed. This behavior can be explained by quantum beats in the polarization decay of coherently excited singlet and triplet excitons.
