“…SBN single crystals are characterized by the extremely large electro-optical coefficients and high nonlinear optical properties. Doping of the SBN solid solutions by rare-earth and transition metals allows to modify the properties of the crystals and to create new materials for different applications, particularly in the areas of pyroelectricity, piezoelectricity, electro-optics, photorefractive optics and non-linear optics [4][5][6][7].…”

The nominally pure and doped with Ce, Cr, Co strontium-barium niobate crystals of SBN:61 were grown by modified Stepanov technique. The specific features of the technique were studied and growth conditions for obtaining the high homogeneous SBN crystals in bulk-profiled configuration were optimized. The photorefractive and non-linear properties of SBN pure and doped with Ce, Cr and Co were investigated. It was shown that SBN:Ce crystal is an excellent medium for high efficiency holographic information recording. SBN:Cr and SBN:Co crystals are promising photorefractive materials with short response time. The as-grown SBN crystals were also used to demonstrate the diffuse noncollinear second harmonic generation emitted by a random domain SBN structure and Stimulated Raman Scattering and two-photon absorption associated with cubic nonlinear susceptibility of the materials.

“…Ferroelectric crystals of strontium barium niobate Sr x Ba 1−x Nb 2 O 6 (SBN-x) possess an unique set of properties for basic research and many applications (optical, pyro-and piezoelectric) [1][2][3][4][5]. In particular it has anomalous high electrooptic effect at the room temperature.…”

“…In particular it has anomalous high electrooptic effect at the room temperature. Change of relative contents of the proper ions of strontium and barium (0.25 ≤ x ≤ 0.75), and also doping by various impurities lead to wide possibilities of the crystal property control [2][3][4][5]. Disorder in a relative placement of the strontium and barium ions results in degradation of a ferroelectric phase transition [1] and also leads to significant broadening (∼ 80 cm −1 ) and decreasing the peak intensities of Raman lines [6][7][8].…”

Stimulated Raman scattering in the strontium barium niobate SrxBa1−xNb2O6 (SBN x = 0.61) crystal under 18 ps laser pumping at 1064 nm was observed for the first time. Effective Raman oscillation was achieved at the first Stokes Raman component (at the wavelength of 1143 nm) and also at the second Stokes component (at the wavelength of 1230 nm) corresponding to the frequency shift of 640 cm −1 . The steady-state Raman gain coefficient was calculated to be 0.42 cm/GW. The Raman oscillation at the wavelength of 1134 nm corresponding to the frequency shift of 580 cm −1 and also the multistage Raman oscillation at short frequency shift of 92 cm −1 in other pump orientations were observed too.

“…This behavior can be explained in terms of the characteristic thermal hysteresis associated with the first-order ferroelectric transition of SBN. 7 The bistable and reversible optical behavior observed for SBN waveguides can be understood in terms of the creation of a space-charge distribution on either side of the strained HAZ. During irradiation, a highly ionized region is generated in the focal region.…”
