Paper Abstract

Several methods are investigated to avoid undesired erasure during read-out of volume phase holograms stored in photorefractive crystals. We present results on thermal fixing and on the utilization of two-step excitations. Furthermore we propose two new methods to read volume holograms nondestructively using light of low photon energy not sufficient to excite charge carriers.
