Item 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.Item New CdLa2(WO4)4:Nd3+ single crystal for lasers: growth and properties(Видавництво національного університету “Львівська політехніка”, 2009) Baumer, V.
