A mathematical model is developed to account for the fixing and developing behavior of
holographic gratings in photorefractive materials such as LiNbO_3. All transport processes …

Light‐induced charge transport properties of LiNb03 crystals containing Mg dopants as well
as Fe ions in different valence states are studied to obtain quantitative information on the …

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 comparative study is presented of the optical damage induced by green light in LiNbO 3
waveguides prepared by Ti in-diffusion, proton exchange and ion implantation. The methods …

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 steady-state field gratings recorded in photovoltaic photorefractive materials have been
investigated theoretically for high modulation's depths of the light intensity pattern (up to …

In this chapter, the standard model accounting for the photorefractive nonlinearity in a
material is presented. The mathematical formalism of the rate equations has been …

Even though the Kukhtarev model [SOy. Tech. Phys. Lett. 2, 438 (1976); SOy. Phys. Solid
State 16, 2414 (1975); Ferroelectrics 22, 949 (1979); SOY. J. Quantum Electron. 8, 231 …

A model is presented for the time dependence of energy transfer between two incident
beams and the concomitant grating formation in photorefractive materials. The theory …

The erasure kinetics of holographic gratings has been studied as a function of the erasing
wavelength in Fe: LiNbO_3. Sample self-absorption has been rigorously taken into account …
