Abstract
Experimental and theoretical studies of the photovoltaic shift in the posit ion of the diffraction efficiency maximum of holograms recorded in LiNbO3 f or the case of optimal electric field multiplexing are described. The exper imental data are explained using a model in which the bulk photovoltaic fie ld is excited in a crystal that is electrically connected with a low loadin g resistance. We suggest that the surface conductivity of the crystal can p lay an important role in the formation of this effective loading resistance .
