Dielectric response and optical manipulation of charge ordering (CO) in LuFe_2O_4 were investigated by terahertz spectroscopy. Abrupt increase in optical conductivity was observed above the CO transition temperature. Photoabsorption observed immediately (1 ps) after the photoexcitation was attributed to the melting of the CO. The photoinduced phase was revealed to have Drude-like metallic state and anisotropic relaxation dynamics.
