    • 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.

    • Optical properties of spinel based glass-ceramics of the Zno-Al2O3-Ga2O3-SiO2 system doped with Co2+ ions 

      Malyarevich, A.; Yumashev, K.; Dymshits, O.; Alekseeva, I.; Zhilin, A. (БНТУ, 2022)
      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 and its characteristics (absorption recovery time, ground-state and excited-state ...
