Abstract
A novel method to measure a short light pulse using the photorefractive effect is proposed. Since photorefractive crystals are volume holograms, if we assign one axis to time, we can use them as materials which record the change of spatially two dimensional information. We recorded 3.5 ps pulses of a mode-locked Nd:YAG laser in a Fe:LiNbO3 crystal and read out the information by cw He-Ne laser by measuring the amplitude and phase of the diffracted wave.
