Dynamical localization, that is, reduction of the intersite electronic transfer integral t by an alternating electric field, E(omega), is a promising strategy for controlling strongly correlated systems with a competing energy balance between t and the Coulomb repulsion energy. Here we describe a charge localization induced by the 9.3MVcm(-1) instantaneous electric field of a 1.5 cycle (7 fs) infrared pulse in an organic conductor alpha-(bis[ethylenedithio]-tetrathiafulvalene) I-2(3). A large reflectivity change of >25% and a coherent charge oscillation along the time axis reflect the opening of the charge ordering gap in the metallic phase. This optical freezing of charges, which is the reverse of the photoinduced melting of electronic orders, is attributed to the similar to 10% reduction of t driven by the strong, high-frequency (omega >= t/(h) over bar) electric field.
