Заглавие : Structural field of K2Al2B2O7-family [borate] crystals
Коллективы : Nonlinear Optics and Applications (7; 2013 ; Apr. ; 15; Prague)
Место публикации : Proc. SPIE. - 2013. - Vol. 8772. - Ст.877210. - P. - DOI 10.1117/12.2017099
Аннотация: The known crystal structures of borate compounds with general composition AI2MIII 2B2O7 (AI: Na, K, Cs, Rb) have been considered. The structures in space groups P63/m, P-31c, P321 and P21/c have been found depending on cation combination. Criterion k = (r(MIII)+r(B)+2r(O))/r(AI) has been formulated and it controls the formation of trigonal K2Al2B2O7 (KABO) type structure. The existence of noncentrosymmetric KABO-type borates is possible over the range of k = 2.7 – 2.06. This range is promising for searching new borate crystals and solid solutions with pronounced nonlinear optical properties. © (2013) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).

Аннотация: The structures of K 2(1-x)Rb 2xAl 2B 2O 7, x = 0.25, 0.5, 0.75, have been determined in space group P321 through Rietveld analysis of X-ray powder diffraction data. The solubility limit in K 2(1-x)Rb 2xAl 2B 2O 7 crystals has been estimated as x similar to 0.83-0.9. Nonlinear optical properties of KRbAl 2B 2O 7 have been verified by powder Kurtz-Perry method. Mechanisms of structural parameter variation in K 2Al 2B 2O 7 crystal family have been discussed.

Заглавие : Nonlinear backward-wave photonic metamaterials
Место публикации : Adv. Sci.Technol. - 2013. - Vol. 77. - P.246-252. - DOI 10.4028/www.scientific.net/AST.77.246
Аннотация: Novel concepts of nonlinear-optical (NLO) photonic metamaterial are proposed. They concern photonic materials that support backward electromagnetic or vibration waves (BWs) and provide coherent nonlinear-optical energy exchange between ordinary and BWs as applied to three- and four-wave mixing processes. Three different classes of materials which support BWs are considered: plasmonic negative-index (NI) metamaterials (NIMs), metamaterials with specially engineered spatial dispersion of the nanoscopic building blocks, such as standing carbon nanotubes, and crystals that support optical phonons with negative group velocity. The possibility to exploit ordinary crystals instead of plasmonic NLO metamaterials that are very challenging to engineer is proposed. It is shown that extraordinary nonlinear optical frequency-conversion propagation processes attributed to NIMs can be mimicked in the proposed metamaterials. It is also shown that the detrimental effects of strong losses can be mitigated in the short-pulse regimes, which exhibit exotic properties when ordinary and BWs are involved in the NLO coupling. Comparative review of unparallel properties of coherent energy exchange between ordinary and backward electromagnetic waves in NIMs and between ordinary electromagnetic waves coupled through backward vibration waves is given. Unique photonic devices are proposed.

Аннотация: Room-temperature modification of potassium oxyfluorotungstate, G(2)-K3WO3F3, has been prepared by low-temperature chemical route and single crystal growth. Wide optical transparency range of 0.3-9.4 mu m and forbidden band gap E-g=4.32 eV have been obtained for G(2)-K3WO3F3 crystal. Meanwhile, its electronic structure has been calculated with the first-principles calculations. The good agreement between the theorectical and experimental results have been achieved. Furthermore, G(2)-K3WO3F3 is predicted to possess the relatively large nonlinear optical coefficients. (C) 2012 Elsevier Inc. All rights reserved.

Ключевые слова (''Своб.индексиров.''): nonlinear photonic crystal--strontium tetraborate--second harmonic generation--random quasi phase matching
Аннотация: Random quasi-phase-matched frequency doubling of fs pulses to the deep UV was obtained in 1D nonlinear photonic crystal (NPC) of strontium tetraborate. Tuning range of generated radiation is from 187.5 to 215 nm. The spectrum of generated radiation consists from series of peaks with the width of order of 1 angstrom. These peaks are the manifestation of the NPC band structure. Using fs oscillator as the fundamental radiation source, maximum average power of generated radiation is of order 1 mu W, the enhancement factor with respect to monodomain sample being of order of several hundred. The red rotational shift of NPC band structure is experimentally demonstrated.
