    Comparison of Nd:YAG optical ceramics produced by different sintering routes
    (Видавництво Львівської політехніки, 2012) Doroshenko, А. G.; Kosyanov, D. Yu.; Маteychenko, P. V.; Matveevskaya, N. A.; Parkhomenko, S. V.; Puzikov, V. M.; Tolmachev, A. V.; Yavetskiy, R. P.; Kopylov, Yu. L.; Kravchenko, V. B.
    Nd:YAG ceramics were fabricated by solid-state reactive sintering of commercial powders and vacuum sintering of custom made co-precipitated nanopowders. The densities, microstructure, average grain size, residual porosity, optical transmittances of the sintered ceramics were compared. Nd:YAG ceramics produced by solid-state reactive sintering possess higher transmittance compared to vacuum-sintered ceramics from coprecipitated nanopowders, which is however still lower than that of single crystals. The possible ways to improve optical quality of Nd:YAG ceramics are discussed.

    Growth and characterization of pure and Yb-Doped Ca9Y(VO4)7 single crystals
    (Видавництво Львівської політехніки, 2012) Kosmyna, M. B.; Mateychenko, P. V.; Nazarenko, B. P.; Puzikov, V. M.; Shekhovtsov, A. N.; Paszkowicz, W.; Ermakova, O.; Romanowski, P.; Yasukevich, A. S.; Kuleshov, N. V.; Kisel, V. E.; Gulevich, A. E.; Demesh, M. P.
    Pure and Yb-doped Ca9Y(VO4)7 (CYVO) single crystals were grown using the Czochralski method. Their crystal structure was determined using powder diffraction and the defect structure was characterized using highresolution diffraction. The undoped crystal is found to be composed of a transparent and an opaque parts. In the latter, yttrium-rich inclusions were detected. Spectral-kinetic characteristics of Yb3 -doped crystals is reported.
