    • Continuous wave and passively q-switched Er,Yb:GdMgB5O10 microchip lasers 

      Gorbachenya, K.; Volkova, E.; Maltsev, V.; Koporulina, E.; Kisel, V. (Интегралполиграф, 2024)
      We demonstrate continuous wave and passively Q-switched Er,Yb:GdMgB5O10 microchip lasers emitting in the spectral range of 1.5–1.6 ?m. A maximal output power of 220 mW was obtained at 1568 nm at absorbed pump power of 2.3 W with the slope efficiency of 18 %. By using of MBE-grown Cr:ZnS thin layer as a saturable absorber laser pulses with duration of 24 ns and energy of 3 ?J at ...

    • Crystal growth and spectroscopic characterization of Yb:YMgB5O10 

      Gorbachenya, K.; Yasukevich, A.; Lazarchuk, A.; Kisel, V.; Shishko, T.; Volkova, E.; Maltsev, V.; Koporulina, E.; Yapaskurt, V.; Kuzmin, N.; Ksenofontov, D.; Mitina, D.; Jiliaeva, A.; Kuleshov, N. (БНТУ, 2022)
      A transparent Yb:YMgB5O10 single crystal with dimensions up to 25×23×25 mm was grown. Absorption cross-section spectra were produced. The luminescence spectra of the Yb: YMgB5O10 crystal were measured in the spectral range of 950–1100 nm. The luminescence kinetics of the 2F5/2 energy level were investigated and the lifetime was determined.
