Аннотация: Čerenkov-type second harmonic generation of femtosecond pulses in random one-dimensional nonlinear photonic crystal of strontium tetraborate is investigated experimentally and theoretically. Sidebands in angular-spectral dependence of generated second harmonic were detected and found to be in perfect agreement with calculations. Spectral maximum of generated radiation experiences deviation from Čerenkov relation due to influence of nonlinear photonic crystal structure. Pulse duration and local spectrum of Čerenkov second harmonic are measured and found to be in fair agreement with each other.

Аннотация: The crystal lattice vibrational frequencies in the center of the Brillouin zone have been determined with the Raman spectroscopy method. The lattice vibrational frequencies, the phonon density of states, elastic and piezoelectric moduli, Born dynamic charges, and high-frequency dielectric constant have been calculated using the density functional method. All calculated quantities have been compared to the experimental data. A model of a nonpolar paraelectric phase for this compound, as well as a mechanism of the formation of domain in it, has been proposed. The polarization in the experimentally observed polar phase has been calculated.

Аннотация: Noncollinear frequency doubling in a random nonlinear photonic crystal of strontium tetraborate via nonlinear diffraction from virtual beam is investigated. This effect is shown to be useful for ultrashort pulses characterization in broad spectral range. Nonlinear photonic crystals of strontium tetraborate are a promising medium for ultrafast diagnostics in short-wavelength applications. (C) 2011 American Institute of Physics.

Аннотация: Efficient tunable femtosecond phase-matched noncollinear second-harmonic generation in randomized nonlinear photonic crystal of strontium tetraborate is obtained. Spatial spectrum of nonlinear photonic structure is not flat but enables tuning of the harmonic frequency in the range from 355 to 460 nm. The narrowing of the bandwidth of second harmonic is found to be of order of 10-20%. (C) 2009 Elsevier B.V. All rights reserved.

Аннотация: The asymmetric unit of the title compound, beta-SrB4O7, contains five Sr atoms (three located on a threefold rotation axis), twelve B and 21 O atoms. The structure is made up from BO3 triangles and BO4 tetrahedra in a 1:1 ratio. Pairs of BO3 triangles are linked to BO4 tetrahedra via common corners, forming chains. These chains are further linked to adjacent chains through corner-sharing, leading to a three-dimensional framework with channels running parallel to [001]. The Sr2+ ions reside in the channels and exhibit strongly distorted polyhedra The density of the beta-polymorph is considerably lower than that of beta-SrB4O7, which is constructed solely from BO4 tetrahedra.

Аннотация: Random quasi-phase-matching (RQPM) of the second-harmonic generation process is investigated experimentally and theoretically in a strongly randomized spontaneously grown nonlinear photonic crystal structure of strontium tetraborate. The thickness of domains in the structure is measured and employed in calculations of angular and spectral dependences of random quasi-phase-matching. Despite the great scale of randomness, the RQPM effect is preserved. The calculated enhancement factor due to RQPM is in excellent agreement with experiment, and good agreement between calculations and experiment is obtained for the shape of the angular dependence of RQPM. The calculated spectral dependence of RQPM consists of a number of narrow peaks, and a maximum enhancement factor is attained in the near ultraviolet. The band structure of randomized nonlinear photonic crystal is calculated.

Аннотация: Radiation in the range 187.5-215 nm was generated via random quasi-phase-matched frequency doubling of femtosecond laser pulses in nonlinear photonic crystals of strontium tetraborate. Abroad spectrum of fundamental radiation favors the probing of the nonlinear photonic crystal band structure. The red shift of the band structure upon the fundamental wave-vector rotation was observed. No principal limitations of the tuning range at its shorter wavelength boundary from the nonlinear photonic crystal (NPC) material are found. Calculation shows that the NPC structure enables enhancement of nonlinear generation in the vacuum ultraviolet.

Аннотация: The polarized Raman spectra of SrB4O7 (SBO) single crystals are studied in detail in the temperature range of 300–1273 K. The TO, LO, and IO phonon lines of A1, A2, B1, and B2 symmetries of rhombic SBO at 300 K are identified. The behavior of the Raman spectra of SBO crystals is studied upon heating up to their melting. The relation of Raman spectra with the structure of boron–oxygen fragments, as well as the transformation of spectra in the process of melting of SBO crystals, is discussed. © 2016, Pleiades Publishing, Ltd.

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.

Аннотация: The crystallization of SrO center dot 2B(2)O(3) glasses has been studied. Four different crystalline formations were found to form simultaneously and independently on the glass surface: stable alpha-SrB4O7 crystals and metastable crystalline forms (beta-SrB4O7, Sr4B14O25, and spherulites (presumably, mixtures of crystalline phases)). The ranges of thermal stability of the newly formed metastable phases have been established using thermal analysis.

Аннотация: Random nonlinear photonic crystal (NPC) structures formed by as-grown domains in a non-ferroelectric strontium tetraborate (SBO) are investigated. The domain shape and orientation are similar to those in ferroelectric KTP. Nonlinear diffraction is the simplest way to detect, evaluate and characterize these structures. Reciprocal superlattice vectors spectra of NPC in SBO are very wide and enable broadband efficiency enhancement of nonlinear optical processes. Second harmonic (SH) generation of femtosecond Ti:sapphire oscillator radiation with 1.9% efficiency is obtained using nonlinear diffraction geometry. Random quasi phase matched generation at the wavelengths of fourth harmonic of Ti:sapphire laser is obtained with average power up to 1 ?W. © 2010 Copyright SPIE - The International Society for Optical Engineering.
