In summary, we have developed a new imaging technique for photo-induced index change in photorefractive crystals. Formation of waveguide structures were successfully visualized both spatially and temporally. This technique will be an useful tool for monitoring versatile photorefractive phenomena, including photorefractive grating formation.
