    • 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 ...

    • 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 ...

    • In-Band Pumped Continuous-Wave Lasers Based on Ho:KY(WO4)2 Crystal and Ho:KGdYbY(WO4)2 Epitaxial Layer 

      Dernovich, O. P.; Gusakova, N. V.; Kisel, V. E.; Kravtsov, A. V.; Guretsky, S. A.; Pavlyuk, A. A.; Kuleshov, N. V. (БНТУ, 2020)
      2 μm lasers are in demand for a number of practical applications, such as environmental monitoring, remote sensing, medicine, material processing, and are also used as a pump sources for optical parametric generators. Crystals of double potassium tungstates doped with ions of rare-earth elements were shown to be promising materials both for the creation of classical solid-state ...

    • Thermal lensing measurements in the anisotropic laser crystals under diode pumping 

      Loiko, P. A.; Savitski, V. G.; Yumashev, K. V.; Kuleshov, N. V.; Pavlyuk, A. A. (БНТУ, 2012)
      An experimental setup was developed for thermal lensing measurements in the anisotropic di-ode-pumped laser crystals. The studied crystal is placed into the stable two-mirror laser cavity operating at the fundamental transversal mode. The output beam radius is measured with re-spect to the pump intensity for different meridional planes (all these planes contain the light propagation ...Nm.
