We develop a theory of high-temperature photorefractive phenomena in LiNbO 3 crystals
related to the problem of thermal fixing and storage of optical information. The theory covers …

The photorefractive effect of undoped LiNbO 3 crystals of high purity is studied by means of
two-photon excitation of picosecond light pulses. We show that two-photon photorefractive …

The thermal and optical stability of photorefractive holograms written in iron-doped LiNbO 3
have been measured over the temperature range from 50 to 165 degrees C. In each case …

The optically induced index change in doped LiNbO3 has been investigated by a
holographic technique with several laser lines between 458 nm and 528 nm. The …

The photorefractive properties of LiNbO 3∶ Fe and LiNbO 3∶ Cu have been studied in
combination with optical absorption-, Mössbauer-and EPR-measurements. The charge …

Single crystals of LiNbO 3 doped with Mn, Fe, or Cu have been reduced or oxidized at 800°
C. Changes in the optical absorption spectra and in the photorefractive sensitivity have been …

The photorefractive response time of LiNbO_3 crystal is of the order of minutes, and such a
long response time limits the crystal's practical applications. We report the photorefractive …

Photorefractive effect has been measured in LiNbO3: Fe at high temperature in the range
180–300° C. At temperatures higher than 230° C only transient effects can be observed. The …
