    • Continuous-wave Laser on Er,Yb-Codoped Pentaborate Crystal 

      Gorbachenya, K. N.; Kisel, V. E.; Deineka, R. V.; Yasukevich, A. S.; Kuleshov, N. V.; Maltsev, V. V.; Mitina, D. D.; Volkova, E. A.; Leonyuk, N. I. (БНТУ, 2019)
      We report, for the first time to our knowledge, a diode-pumped continuous-wave microchip Er,Yb:YMgB5O10 laser. The purpose of this work was to study the growth technique, spectroscopic properties and continuous-wave laser performance of Er3+,Yb3+:YMgB5O10 novel crystal. Absorption and luminescence spectra as well as kinetics of luminescence decay were studied. Ytterbiumerbium ...

    • Determination of the Concentration of Tm3+ and Ho3+ Ions in the Glass and Crystalline Phases in Oxyfluoride Glass Ceramics by Absorption Spectra Analysis 

      Yasukevich, A. S.; Kisel, V. E.; Trusova, E. E.; Rachkovskaya, G. E.; Zakharevich, G. B.; Podbolotov, K. B.; Gurin, V. S. (БНТУ, 2024)
      Optical glass ceramics based on oxyfluoride glasses activated by rare earth ions have attractive properties for development of lasers and near-infrared amplifiers, since they combine properties of fluoride crystals with low phonon frequencies and chemical and mechanical properties of oxide matrices. Spectroscopic properties of activator ions in crystalline and glass phases of ...

    • Er,Yb:Ca3RE2(BO3)4 (RE=Y, Gd) – Novel 1.5 μm Laser Crystals 

      Gorbachenya, K. N.; Deineka, R. V.; Kisel, V. E.; Yasukevich, A. S.; Shekhovtsov, A. N.; Kosmyna, M. B.; Kuleshov, N. V. (БНТУ, 2019)
      The search for new crystalline host materials for the usage in lasers emitting in the eye-safe spectral range of 1.5–1.6 μm is an important task. The aim of this work was to study the growth technique, spectroscopic properties and laser characteristics of new active media – crystals Er3+,Yb3+:Ca3RE2(BO3)4 (RE=Y, Gd). Calcium-yttrium Er3+,Yb3+:Ca3Y2(BO3)4 (CYB) and calcium-gadolinium ...

    • 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 ...
