Optimal conditions for thermal fixing of volume holograms in Fe:LiNbO3 crystals.

چکیده
We analyze and compare two typical recording and thermal fixing procedures of a volume hologram in a Fe:LiNbO(3) crystal (low-high-low procedure and high-low procedure). We consider the kinetics of the recording, compensating, and developing processes by taking into account the ratio of the conductivities between the protons and the electrons as a function of temperature. From the analysis the optimal environmental conditions (in terms of the fixing temperature and the compensation time) for each fixing procedure can be deduced for a crystal with given material parameters.

Selective page-addressable fixing of volume holograms in Sr(0.75)Ba(0.25)Nb(2)O(6) crystals.
We demonstrate selective fixing of volume holograms in photorefractive media. Each holographic page may be fixed individually and overwritten without destroying the other fixed pages. We present experimental results describing this process in Cr-doped Sr(0.75)Ba(0.25)Nb(2)O(6) at room temperature, with hologram lifetimes exceeding 100 days during continuous readout with an intense beam (1 W/cm(...

The transient interaction between a refraction index grating and light beams during simultaneous writing and thermal fixing of a photorefractive hologram is investigated. With a diffusionand photovoltaic-dominated carrier transport mechanism and carrier thermal activation (temperature dependent) considered in Fe:LiNbO3 crystal, from the standpoint of field-material coupling, the theoretical the...
متن کاملFixing of photorefractive volume holograms in K(1-y)Li(y)Ta(1-x)O(3).
We report the fixing of photorefractive holographic gratings with high efficiency in a sample of K(1-y)Li(y)Ta(1-x)Nb(x)O(3) doped with Cu, V, and Ti. Holograms are thermally fixed through the screening of a photorefractive space-charge f ield by a nonphotoactive species at elevated temperatures. Fixed holograms are revealed by illumination at lower temperatures. Diffraction efficiencies of 25%...
متن کاملThermal fixing of 10,000 Holograms in LiNbO3:Fe.
We discuss thermal fixing as a solution to the volatility problem in holographic storage systems that use photorefractive materials such as LiNbO(3):Fe. We present a systematic study to characterize the effect of thermal fixing on the error performance of a large-scale holographic memory. We introduce a novel, to our knowledge, incremental fixing schedule to improve the overall system fixing ef...
متن کاملTemperature dependence of absorption in photorefractive iron-doped lithium niobate crystals
We present experimental data showing a significant dependence of light absorption on temperature in photorefractive LiNbO3 :Fe crystals. The results are successfully explained by assuming that the widths of the Fe absorption bands in the visible and in the infrared spectral region depend on temperature. The findings are of relevance for thermal fixing of holograms. Furthermore, a temperature-in...
