In this article, we review recent progress in the area of photorefractive polymers.
Photorefractive (PR) polymers are multifunctional materials which combine …

We show that absorbing photorefractive materials characterized by a space-charge
exponential relaxation time law exhibit an overall hologram optical erasure that is described …

Charge transfers between traps in undoped Bi12GeO20 (BGO) crystals have been
investigated so as to complete our previous studies concerning the mechanism of the …

The nonlinear diffraction property of a volume grating written by two-wave mixing in a cerium-
doped potassium sodium strontium barium niobate crystal is applied in a coherent image …

The problem of maximising the relative intensity of the signal optical wave in the course of
two-wave mixing was solved taking into account the self-diffraction in a Bi 12 SiO 20 …

Решена задача максимизации относительной интенсивности сигнальной световой
волны при двухволновом взаимодействии с учетом самодифракции в пьезокристалле …

A two-level model of a simultaneous read–write of holographic gratings in photorefractive
crystals has been developed for the nonstationary case at the applied electric field and …

El conocimiento del régimen no lineal, donde se generan las redes fotorrefractivas
armónicas está prácticamente limitado a un conocimiento aproximado del modelo de …
