    • Er,Yb:ReGa3(BO3)4 (Re = Y, Gd) laser crystals 

      Maltsev, V. V.; Volkova, E. A.; Koporulina, E. V.; Mitina, D. D.; Kosorukov, V. L.; Jiliaeva, A. I.; Naprasnikov, D. A.; Gorbachenya, K. N.; Kisel, V. E. (БНТУ, 2023)
      Phase relationships in the ErxYbyY1-x-yGa3(BO3)4-Bi2O3-B2O3-(Y,Er,Yb)2O3–Ga2O3 and ErxYbyGd1-x-yGa3(BO3)4-Bi2O3-B2O3-(Gd,Er,Yb)2O3 – Ga2O3 (x = 0.02, y = 0.11 at.%) system were studied in the temperature range from 1000 to 900 оС. Multicomponent melt Bi2O3-Ga2O3-B2O3-(Y,Gd)2O3 were used as reasonable fluxes for high-temperature solution growth of ErxYbyR1-x-yGa3(BO3)4 (R = Y, Gd) ...

    • Spectroscopic properties of nd:LaAl2B3O9 crystal 

      Gorbachenya, K. N.; Polubok, S. V.; Ardashev, V. S.; Maltsev, V. V.; Koporulina, E. V.; Volkova, E. A.; Jiliaeva, A. I.; Afanasiev, A. E.; Naprasnikov, D. A.; Kisel, V. E. (БНТУ, 2025)
      Laser-related spectroscopic properties of Ndx :La1-xAl2B3O9 (x = 0.03-0.06) crystals were determined. The room temperature absorption spectrum was measured in the spectral range of 400-1000 nm. Preliminary studies of the luminescence kinetics of this crystals demonstrate the absence of Nd3+ concentration quenching over the entire doping range investigated. This makes this material ...
