Abstract
Ferroelectric photorefractive Sn2P2S6 crystals become more sensitive t o cw radiation of a Nd3+: YAG laser (lambda = 1.06 mu m) by preexposur e with incoherent white light. Space-charge formation and hologram rec ording are dominated by a diffusionlike charge transport, leading to a n ultimate gain factor for transmission gratings that exceeds 6 cm(-1) at a laser intensity of approximately 50 W/cm(2).
