TY - JOUR AU - Noginova, Natalia E. AB - A transient photo-electric current was investigated in photorefractive crystals of Sr 1-x Ba x Nb 2 O 6 (SBN) and Bi 12 TiO 20 (BTO) as a response to a step-like modulation of the light grating phase. Different dependencies of the photocurrent relaxation time on the grating period were observed for SBN and BTO crystals. It is explained theoretically taking into consideration kinetics of the photoexcitation of carriers, charge transfer and trapping. A number of important parameters characterizing the crystals are estimated.
