“…The growth, decay, and erasure of the grating are reported as functions of the Eu 2 O 3 concentration. In addition, we show that the experimental results are in good agreement with the small modifier diffusion ͑SMD͒ model developed by Dixon et al 12 We also report the ionic conductivity as a function of ͓Eu 2 O 3 ͔, and we discuss its relevance to the FWM results.…”

“…Previous research [1][2][3][4][5][6]11,12 supports the conclusion that the grating consists of a transient and a persistent component of different physical origins. The transient component is due to a population grating in the 5 D 0 metastable state of Eu 3ϩ .…”

“…Laser-induced persistent and transient refractive index gratings in Eu 3ϩ -doped silicate, phosphate, and germanate glasses have been previously reported. [1][2][3][4][5][6][7][8][9][10][11][12] These gratings were formed and detected using the nondegenerate four-wave mixing ͑FWM͒ technique. In all of these studies, the 465.8 nm line of a cw argon laser was used to excite the Eu 3ϩ ions and a He-Ne laser to detect the grating formation.…”

“…This model accounts well for the kinetics of grating formation and decay. 12 This model for the formation of the persistent gratings suggests that varying the Eu concentration will affect the grating efficiencies in two ways. First, Eu is the active element for coupling the optical energy into diffusion of the small modifiers.…”

Phys. 97, 069901 (2005); 10.1063/1.1849815Low-temperature dynamic properties of photorefractive grating in potassium-strontium-sodium-barium-niobate crystalWe report a systematic study of a grating formation in which the ͓Eu 2 O 3 ͔ in sodium-magnesiumaluminosilicate glasses is varied from 0.76 to 8.11 mol %. The growth, decay, and erasure of the grating are reported as functions of the ͓Eu 2 O 3 ͔. The maximum persistent change in the index of refraction was 3ϫ10 Ϫ5 . The persistent change in the index of refraction was initially a quadratic function of the ͓Eu 2 O 3 ͔ and showed a limiting behavior at the highest ͓Eu 2 O 3 ͔. The transient change in the index of refraction ⌬n tran was a quadratic function of ͓Eu 2 O 3 ͔ throughout the range of concentrations studied here. The grating buildup rate increased linearly with ⌬n tran . The results of this study are consistent with the model published recently by Dixon et al. Ionic conductivities were also measured to help separate the effect of the Eu 3ϩ on the glass network from its active role in transferring the optical energy into ionic motion.

Public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. AUTHOR(S) ON REPRINT PERFORMING ORGANIZATION NAMES(S) AND ADDRESS(ES)Oklahoma State University Clear holographic images were stored using a total writing power of 5 mW and an exposure time of 20 s. In addition, clear holograms were recorded using an exposure time of 200 ms when 100 mW of the writing power was used. The exposure time and the writing power required for obtaining clear holographic images are dependent on the Eu 3+ concentration.
