Summary form only given. Photorefractive gratings recorded in LiNbO/sub 3/ are usually volatile: the grating buildup rate is equal to the grating erasure rate if the recording intensity is equal to the erasing intensity. On the other hand, high asymmetry in the grating buildup and erasure rates is desired in some applications. For example, holographic memory applications require nonvolatility of recorded gratings during readout while they require the recording sensitivity as high as possible. Here we report on the near-infrared one-color photorefractivity and the observation of high asymmetry in the grating buildup and erasure rates in LiNbO/sub 3/:In,Fe.
