  • Radial Distribution Study of Vitreous Barium Borosilicate G
    JOURNAL OF RESEARCH of the National Bureau of Standards—A. Physics and Chemistry Vol.l67Af No. 1, January-February 1963 Radial Distribution Study of Vitreous Barium Borosilicate G. J. Piermarini* and S. Block (September 19, 1962) An X-ray diffraction study of a barium borosilicate glass consisting of 24 mole percent barium oxide, 40 mole percent boric oxide, and 36 mole percent silicon dioxide has been per- formed. Resulting atomic radial distribution functions give the following average inter- atomic distances: Si-O, 1.6 A; Ba-O, 2.8 A; Ba-Ba, 4.7 A; and Ba-Ba, 6.8 A. From the 4.7 A Ba-Ba separation a Ba-O-Ba bond angle of about 115° has been calculated. The observed average barium separations are in partial agreement with that predicted by Levin and Block on the basis of a structural interpretation of immiscibility data. A proposed coordination change by Levin and Block for the barium atoms in the system has been confirmed, but the details of the coordination change mechanism have not. Combining the results of the radial distribution study and immiscibility data on the barium borosilicate modifier-rich liquid at maximum barium oxide content has indicated that approximately 16.75 mole percent barium oxide is involved in the 4.7 A separation and 8.25 mole percent is associated with the 6.8 A separation. A mechanism which allows the composition of the modifier-rich liquids in the ternary system to be calculated has been presented. The calculated composition has been found to agree well with the experimental value.

In SPDC, a pump photon interacts with a non-linear optical crystal and splits into two entangled photons called the signal and the idler photons. The SPDC process has been studied extensively in the last few decades for various pump and crystal configurations, and the entangled photon pairs produced by SPDC have been used in numerous experimental studies on quantum entanglement and entanglement-based real-world quantum-information applications.

  • Generation of Green Second Harmonic Radiation in LBO, Bibo, KTP, And
    Generation of green second harmonic radiation in LBO, BiBO, KTP, and PPLN crystals using passively Q-switched sub-nanosecond microchip laser by Kostyantyn Sukhoy A Thesis submitted to the Faculty of Graduate Studies of The University of Manitoba in partial fulfillment of the requirements for the degree of Master of Science Department of Electrical and Computer Engineering University of Manitoba Winnipeg, Manitoba Canada Copyright © 2011 by Kostyantyn Sukhoy Author’s Declaration I hereby declare that I am the sole author of this thesis. This is not a finalized copy of my thesis. This is a nearly finalized draft of my thesis submitted to my examining committee for their consideration. I understand that an electronic copy of the finalized draft of my thesis may be made electronically available to the public. II Abstract A sub-nanosecond green laser source has big demand in such fields like spectroscopy, micromachining, fluorescence imaging, and laser displays. Most often green light is produced by frequency doubling of pulsed laser sources based on Nd3+-ion or Yb3+-ion doped gain media that oscillate in the near-IR range. For creating compact and relatively small source of green light suitable for broad type of applications a passively Q-switched Nd:YAG microchip laser (Teem Photonics) operating at 1064 nm with 6.9 kHz repetition rate was chosen. It delivers 560 ps long pulses with 10 µJ energy, corresponding to an average output power of 69 mW. Crystals of BiBO, KTP, LBO, and PPLN were chosen for frequency doubling. Main goal of this work was to study the characteristics of these crystals under similar experimental conditions and to select the most efficient one for this task.

  • Crystallization Behavior of New Transparent Glass-Ceramics Based on Barium Borate Glasses
    Journal of the Ceramic Society of Japan 116 [5] 624-631 2008 Paper Crystallization behavior of new transparent glass-ceramics based on barium borate glasses Fatma Hassan MARGHA,*,** Salwa Abdel-Hameed Mohamed ABDEL-HAMEED,* Nagwa Abd El-Shafy GHONIM,* Shigeo SATOKAWA**,† and Toshinori KOJIMA** *Glass Research Department, National Research Center, Dokki, Cairo 12622, Egypt **Department of Materials and Life Science, Faculty of Science and Technology, Seikei University, Tokyo 180-8633, Japan This paper describes the preparation of several new transparent and very fine crystal glass-ceramics from the BaO–B2O3 system utilizing an appropriate additive of fluorides, partial replacement of B2O3 by SiO2, and introducing nucleating agents, such as TiO2. The physical properties of the prepared materials and the changes with varying base glass compositions and heat treatment programs were investigated. The thermal behavior and microstructure of the developed phases were characterized using DTA, XRD, and SEM. Glass-ceramics with marked transparency were prepared. These transparent derivatives owe their transparency to the distinctive properties of the nano-crystalline samples. The dielectric constant of transparent glass- ceramics samples at 100 kHZ were between 14–20, which is very suitable for a wide range of applications, such as the high- – speed switching of large-scale integrators. It was found that the addition of F and SiO2 greatly influenced the transparency of the produced glass-ceramics. Also, the addition of TiO2 greatly enhanced transparency, in spite of increasing cutoff in the UV region to a higher wavelength. ©2008 The Ceramic Society of Japan. All rights reserved.

  • A Contribution to the Development of Wide Band-Gap Nonlinear Optical and Laser Materials
    AN ABSTRACT OF THE THESIS OF Jennifer L. Stone-Sundberg for the degree of Doctor of Philosophy in Chemistry presented on December 3, 2001. Title: A Contribution to the Development of Wide Band-Gap Nonlinear Optical and Laser Materials Redacted for privacy Abstract approved: Douglas A. Keszler The primary focus of this work is on examining structure-property relationships of interest for high-power nonlinear optical and laser crystals. An intuitive and simply illustrated method for assessing the nonlinear optical potentialofstructurallycharacterizednoncentrosymmetricmaterialsis introduced.This method is applied to materials including common quartz and tourmaline and then extended to synthetic materials including borates, silicates, aluminates, and phosphates. Particularly,the contributions of symmetric tetrahedral and triangular anionic groups are inspected.It is shown that both types of groups significantly contribute to the optical frequency converting abilities of noncentrosymmetric crystals.In this study, several known materials are included as well as several new materials.The roles of the orientation, composition, and packing density of these anionic groups are also discussed. The structures and optical properties of the known materials BPO4, NaAlO2, LaCa4O(B03)3, and tourmaline; the new compounds Lao.8Y0.2Sc3(B03)4 and Ba2B10O17; and the laser host Sr3Y075Yb025(B03)3 are described.

The optimal thicknesses of those crystals to avoid any pump pulse depletion for a fundamental-mode laser pulse having a high intensity and a long pulsewidth was calculated as a function of the intensity and the pulsewidth of the fundamental mode. Also, for short-pulse operation, thickness limits are calculated for conditions under which no pulse dispersion due to group velocity mismatch is observed. Finally, the fluctuation of second-harmonic yield due to temperature variations which introduce a refractive-index change is calculated, and the effective temperature ranges are demonstrated for room-temperature operation.

  • Crystal Growth of Multifunctional Borates and Related Materials
    crystals Editorial Crystal Growth of Multifunctional Borates and Related Materials Nikolay I Leonyuk Department of Crystallography and Crystal Chemistry, Moscow State University, 119992 Moscow, Russia; [email protected] Received: 15 March 2019; Accepted: 19 March 2019; Published: 21 March 2019 Keywords: crystal growth; crystallography; crystal chemistry; borates; multifunctional materials Crystalline materials play an important role in modern physics and electronics. Therefore, the demand for crystals with functional properties is increasing strongly, due to the technical advance in different fields: telecommunications, computer devices, lasers, semiconductors, sensor technologies, etc. At the first stage, natural minerals (e.g., quartz) were widely used as piezoelectric and optical material. Later on, after the creation of the first laser, interactions between lasers and materials have been investigated: radiation at the double the frequency of a ruby laser was observed as the fundamental light passing through a quartz crystal [1]. This phenomenon became a substantial contribution to the field of quantum electronics and nonlinear optics. However, natural single crystals usually have insufficient purity, size, occurrence, and homogeneity, or do not even exist in nature. That is why the material scientists began to develop important basic materials with the desirable properties. As an example, at the beginning of the 1960s, this resulted in Czochralski growth of Y3Al5O12 crystals, referred to as YAG, which is the progenitor of the large group of synthetic materials belonging to the structural type of natural garnet family A3B2(SiO4)3 [2]. Owing to a reasonable growth technology, these crystals and their numerous derivatives including transparent nano-ceramics are dominating the elemental base for solid-state laser engineering and various practical applications.

  • Borates—Crystal Structures of Prospective Nonlinear Optical Materials: High Anisotropy of the Thermal Expansion Caused by Anharmonic Atomic Vibrations
    Review Borates—Crystal Structures of Prospective Nonlinear Optical Materials: High Anisotropy of the Thermal Expansion Caused by Anharmonic Atomic Vibrations Rimma Bubnova 1,2,*, Sergey Volkov 1, Barbara Albert 3 and Stanislav Filatov 2 1 Institute of Silicate Chemistry, Russian Academy of Sciences, Makarov Emb. 2, St. Petersburg 199034, Russia; [email protected] 2 Department of Crystallography, Institute of Earth Sciences, St. Petersburg State University, University Emb. 7/9, St. Petersburg 199034, Russia; [email protected] 3 Eduard Zintl-Institute of Inorganic and Physical Chemistry, Technische Universität Darmstadt, Alarich-Weiss-Str. 12, 64287 Darmstadt, Germany; [email protected] * Correspondence: [email protected]; Tel.: +7-981-181-3262 Academic Editors: Ning Ye and Rukang Li Received: 7 February 2017; Accepted: 16 March 2017; Published: 22 March 2017 Abstract: In the present study the thermal structure evolution is reviewed for known nonlinear optical borates such as β-BaB2O4, LiB3O5, CsLiB6O10, Li2B4O7, K2Al2B2O7, and α-BiB3O6, based on single-crystal and powder X-ray diffraction data collected over wide temperature ranges. Temperature-dependent measurements of further borates are presented for the first time: α-BaB2O4 (295–673 K), β-BaB2O4 (98–693 K), LiB3O5 (98–650 K) and K2Al2B2O7 (98–348 K). In addition to the established criteria for nonlinear optical (NLO) properties of crystals, here the role of the anisotropy and anharmonicity of the thermal vibrations of atoms is analysed as well as changes in their coordination spheres and the anisotropy of the thermal expansion of the crystal structure. Non-centrosymmetric borates, especially those that have NLO properties, often show distinct anisotropies for each cation in comparison to centrosymmetric borates.

  • Compositional Effect of Barium Ions (Ba2+) on Ultrasonic, Structural and Thermal Properties of Leadborate Glasses
    International Journal of Innovative Technology and Exploring Engineering (IJITEE) ISSN: 2278-3075, Volume-9 Issue-1, November 2019 Compositional Effect of Barium Ions (Ba2+) on Ultrasonic, Structural and Thermal Properties of LeadBorate Glasses R. Ezhil Pavai, P. Sangeetha, L. Balu preparing glasses by alone, it is used to behave as a network Abstract: Glasses of the formula 68B2O3-(32-x)PbO-xBaO (0≤ x former/modifier in glass matrices and also addition to glass ≤ 12) were synthesized by standard melt quench technique and network, stabilizes the glass [8, 9]. Moreover doping with investigated their properties using XRD, ultrasonic, FT-IR and barium ions, these glasses show low dispersion, co-efficeint DTA studies. No sharp peaks are existing in the XRD spectra and of thermal expansion and melting point as well as high the broad halo appeared around 2θ≈30o, which reflects the characteristics of amorphous nature. Density decreases due to the refraction and electric resistance [10, 11]. The authors were replacement of higher molar mass by lower molar mass. The attempted to synthesis and characterize the BaO doped B2O3 ultrasonic velocity varies with the gradual substitutions of barium – PbO glasses by using several techniques such as XRD, ions in leadborate host glass matrix. The variations in elastic ultrasonic velocity, DTA and FT-IR. moduli such as L, G, K and E), Poisson’ sratio(), acoustic impedance(Z), microhardness (H) and Debye temperature II. EXPERIMENTAL (θD)were observed which resulted in compact glasses. The functional groups of prepared glasses were studied by FTIR A. Sample preparation analysis and BO4 structural units enhanced with decreasing BO3 Glasses of formula 68B2O3-(32-x)PbO-xBaO were structural units.
