    • 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.

    • Spectroscopy of Tm:KY(WO4)2 crystal grown by the modified Czochralski method 

      Gusakova, N.; Gorbachenya, K.; Kisel, V.; Yasukevich, A.; Guretskii, S.; Trukhanova, E.; Kravtsov, A.; Karpinsky, V.; Ozen, Y.; Ozcelik, S.; Kuleshov, N. (БНТУ, 2021)
      Tm3+:KY(WO4)2 (KYW) single crystals were grown by the modified Czochralski method. Laser-related spectroscopic properties of Tm3+:KYW crystal: absorption and luminescence spectra as well as kinetics of luminescence decay were studied.

    • 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.
