Crystal growth and spectroscopic characterization of Yb:YMgB5O10
Gorbachenya, K.; Yasukevich, A.; Lazarchuk, A.; Kisel, V.; Shishko, T.; Volkova, E.; Maltsev, V.; Koporulina, E.; Yapaskurt, V.; Kuzmin, N.; Ksenofontov, D.; Mitina, D.; Jiliaeva, A.; Kuleshov, N. (БНТУ, 2022)A transparent Yb:YMgB5O10 single crystal with dimensions up to 25×23×25 mm was grown. Absorption cross-section spectra were produced. The luminescence spectra of the Yb: YMgB5O10 crystal were measured in the spectral range of 950–1100 nm. The luminescence kinetics of the 2F5/2 energy level were investigated and the lifetime was determined.2022-12-28 -
Thermal expansion of KYbXY1-X(WO4)2 crystals
Yumashev, K.; Trusova, E.; Guretskii, S.; Karpinsky, D.; Trukhanova, K.; Kuleshov, N.; Malyarevich, A. (БНТУ, 2022)Average and differential linear thermal expansion coefficients of KYbxY1-x(WO4)2 crystals are determined in the directions of the optical indicatrix axes Np, Nm and Ng using dilatometric technique. Dependence of the average and differential linear thermal expansion coefficients on the temperature in the range of 75–290 C and ytterbium contains x from 0 to 1.0 are discussed.2022-12-28
