The theoretical analysis of unstationary holographic recording in photorefractive crystals
under an external alternating electric field is presented. In particular, a step-like ac field …

Persistent holograms are recorded locally with red light in a LiNbO_3 crystal doped with Mg
and Fe. Selective erasure is realized by use of a focused UV sensitizing light. We …

We investigate non-volatile holographic data storage in photorefractive lithium niobate
crystals. Infrared picosecond laser pulses are used to write holograms after sensitizing the …

In a recent paper [1] we analyzed the use of fringe-locked holographic recording in Bi 12 SiO
20 and concluded that this new technique was a simple adaptive means to match the …

The paper examines theoretical and experimental results on the diffraction-efficiency
enhancement of amplitude holograms recorded by He-Ne laser in additively colored KBr …

The photorefractive properties of lithium niobate crystals doped with manganese (Mn) have
been investigated. It is found that the effect of dark decay due to electron tunneling, which is …

A Q-switched frequency-doubled Nd: Y AG laser was used to record holograms in LiNbO):
Fe. For 1% diffraction efficiency, only 50 mJ/cm2 was needed, as compared to 500 mJ/cm2 …

In this paper a method to obtain very high diffraction efficiency fixed holograms in lithium
niobate is presented. The procedure consists in a first step of high temperature recording …
