    • Compact 0.7 mJ/11 ns eye-safe erbium laser 

      Vitkin, V. V.; Polyakov, V. M.; Kharitonov, A. A.; Buchenkov, V. A.; Rodionov, A. Yu.; Zhilin, A. A.; Dymshits, O. S.; Loiko, P. A. (2016)
      We report on the development of a compact diode-end-pumped eye-safe (similar to 1.54 mu m) passively-cooled Er, Yb:glass laser. The design of this laser is facilitated by the use of a double-pass pumping scheme and a special ZrO2 diffuse reflector for a uniform pump distribution. In the free-running mode, this laser generates 8.2 mJ/3 ms pulses with a slope efficiency of 15%. ...

    • Structure and nonlinear optical properties of novel transparent glass-ceramics based on Co2+:ZnO nanocrystals 

      Loiko, P. A.; Dymshits, O. S.; Vitkin, V. V.; Skoptsov, N. A.; Zhilin, A. A.; Shemchuk, D. V.; Tsenter, M. Ya.; Bogdanov, K. V.; Malyarevich, A. M.; Glazunov, I. V.; Mateos, X.; Yumashev, K. V. (2016)
      Transparent glass-ceramics (GCs) based on Co2+:ZnO nanocrystals (mean diameter, 11 nm) are synthesized on the basis of cobalt-doped glasses of the K2O–ZnO–Al2O3–SiO2 system. For these GCs, the absorption band related to the 4A2(4F) → 4T1(4F) transition of Co2+ ions in tetrahedral sites spans until ~1.73 μm. Saturation of the absorption is demonstrated at 1.54 μm, with a saturation ...
