    • Efficient 1 W continuous-wave diode-pumped Er,Yb:YAl3(BO3)4 laser 

      Tolstik, N. A.; Kurilchik, S. V.; Kisel, V. E.; Kuleshov, N. V.; Maltsev, V. V.; Pilipenko, O. V.; Koporulina, E. V.; Leonyuk, N. I. (Optical Society of America, 2007)
      We report the spectroscopy and high-power continuous-wave (CW) diode-pumped laser operation of Er:Yb:YAl3(BO3)4 crystal. Absorption and stimulated emission spectra, emission lifetimes, and efficiency of energy transfer from Yb3+ to Er3+ ions were determined. A CW Er:Yb:YAB laser emitting at 1602, 1555, and 1531 nm with output power as high as 1 W and slope efficiency up to 35% ...

    • 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) ...

    • High Power Diode-Pumped Erbium Laser Emitting at Near 1.5 μm 

      Gorbachenya, K. N.; Kisel, V. E.; Yasukevich, A. S.; Koporulina, E. V.; Volkova, E. A.; Maltsev, V. V.; Leonyuk, N. I.; Kuleshov, N. V. (БНТУ, 2021)
      Solid-state lasers emitting in the 1.5–1.6 μm spectral range are very promising for eye-safe laser range finding, ophthalmology, fiber-optic communication systems, and optical location. The aim of this work is the investigation of spectrosposcopic and laser properties of gain medium based on borate crystal for abovementioned lasers. Spectroscopic and laser properties of ...
