Pump-probe reflection spectroscopy was used to analyze the ultrafast photoinduced Mott transition from a charge transfer insulator to a metal in a halogen bridged Ni-chain compound. The spectral weight of the gap transition was found to be transferred to the inner gap region upon irradiation of a 130-femtosecond laser pulse. It was observed that the photogeneration of the metallic state and the subsequent recovery to the original gapped state occur within a few picoseconds.
