摘要: This paper considers two effects for directly studying thick‐phase holograms: (a) coupling between the laser beams used to record a hologram and (b) interference readout beam diffracted within hologram. Both were observed in experiments using single crystals of undoped LiNbO3. The results demonstrate that holograms arise from electric field patterns caused by either diffusion or drift photogenerated free electrons.
