Experimental results on holographic subtraction interferometry in photorefractive lithium
niobate crystals are presented. The dependence of the subtraction operation on the …

We performed recording–readout and bleaching experiment in lightly reduced near-
stoichiometric LiNbO3: Ce: Fe with 532 nm recording beams after UV pre-exposure to get …

Novel holographic recording configurations capable of selective erasure of multiplexed
holograms for data-page rewriting in holographic storage are presented. By using a half …

We show that the oxidation state of Fe in LiNbO_3 has two competing effects on the
diffraction efficiency of multiple holograms in 90°-geometry holographic storage. For crystals …

Nonvolatile photorefractive gratings have been recorded in LiNbO3: Cu: Ce crystals by
using a He–Ne laser (633 nm) for recording and an argon ion laser (458 nm) for sensitizing …

In this paper, the fundamental characteristics of the photorefractive effect, both in bulk
crystals and waveguides, as well as some of the most important photorefractive materials …

Experimental results on real-time holographic interferometry using photorefractive iron-
doped lithium niobate crystals to store the reference holograms are presented. Since the …

This research proposes a method that uses a single object beam to record multiple images
in a photorefractive crystal medium without having to use any reference wave. The object …

Persistent holograms are recorded with red light in lithium niobate crystals doped with
manganese and iron. Different erasure mechanisms are investigated, and a recording …

We propose a mathematical model for the movement in absorbing materials of
photorefractive holograms under feedback constraints. We use this model to analyze the …
