I wish to extend my thanks to Glass et al.[1] for calling my attention to some of the earlier
works on photorefractive sensitivity. After reading these earlier papers, I found that, although …

The initial speed of photorefractive recording and erasure is investigated in two-wave mixing
experiments under carefully controlled grating phase shifts. Results are reported for the full 2 …

The response of photorefractive materials to sinusoidal intensity patterns of high modulation
depths is considered. It is shown that the induced refractive-index response in this regime is …

A general formalism based on the Kukhtarev equations is developed to describe the kinetics
of holographic recording and erasure in unipolar photorefractive materials containing …

We introduce holographic scattering as a technique to determine the activation energy for
thermal fixing of refractive index patterns in photorefractive crystals. After recording a …

A theoretical analysis for the optimization of the selective-erasure process in holographic
photorefractive memories is presented. It is based on the solution of the standard material …

The erasure kinetics of holographic gratings has been theoretically studied for a material
containing two photorefractive species. The approach is an extension of the method …

We report nonstationary photorefractive holograms in absorbing Bi_12TiO_20 samples with
different degrees of hole-electron competition exhibiting resonance peaks due to electron …

The photorefractive effect is a phenomenon in which the local index of refraction is changed
by the spatial variation of the light intensity. Such an effect was first discovered in 1966. The …

We investigate recording and erasure of photorefractive holographic gratings in an undoped
Bi_12TiO_20 crystal in a moderate to high intensity regime of the recording beams at 639.7 …
