We study theoretically the photorefractive response of periodically poled LiNbO3 crystals with dominating photovoltaic transport. Strong suppression of the photorefractive effects at low spatial frequencies (in comparison with the single-domain case) and preservation of these effects for short fringe spacings are shown. We also describe a new kind of photorefractive wave coupling, which is forbidden for single domain crystals. It is characterized by wave propagation angles, dependent on the domain inversion period, and by a large gain factor
