    • Non-linear optical properties of transparent glass-ceramics based on Co2+:Zn(Al,Ga)2O4 spinel nanocrystals 

      Glazunov, I.; Malyarevich, A.; Yumashev, K.; Dymshits, O.; Alekseeva, I.; Zhilin, A. (БНТУ, 2021)
      Transparent glass-ceramics containing Co2+:Zn(Al,Ga)2O4 spinel nanocrystals with sizes of 6–11 nm were studied. Absorption band of the Co2+ ions in the material is shifted to longer wavelengths as compared with glass-ceramics with no Ga2O3 addition. Absorption saturation at 1.54 μm was observed. The developed glassceramics is promising as saturable absorbers for 1.6 μm erbium lasers.

    • Thermo-optic properties of orthorhombic BeAl6O10 crystal 

      Yumashev, K.; Malyarevich, A.; Vilejshikova, E.; Goman, V.; Pavlovski, L. (БНТУ, 2021)
      Thermo-optic coefficients dn/dT were determined for orthorhombic BeAl6O10 crystal for light polarizations E || Np, Nm and Ng in the wavelength range of 0.4–1.1 m. Thermo-optic dispersion formulas for principal thermo-optic coefficients of BeAl6O10 are presented for this spectral range. The principal dn/dT are positive and show a polarization-anisotropy: dnp/dT = 6.4, dnm/dT = ...
