    • Spectroscopy and femtosecond laser performance of Yb3+:YAlO3 crystal 

      Kisel, V. E.; Kurilchik, S. V.; Yasukevich, A. S.; Grigoriev, S. V.; Smirnova, S. A.; Kuleshov, N. V. (Optical Society of America, 2008)
      We report what we believe to be the first demonstration of cw and passively mode-locked Yb3+:YAlO3(Yb:YAP) laser operation under diode pumping. Spectroscopic properties of a 0.6 at.%Yb3+-doped YAP single crystal were investigated. Output power up to 1.2 W with slope efficiency of 64.5% in the cw regime and 225 fs pulse duration with average power of 0.8 W from a mode-locked Yb:YAP ...

    • Spectroscopy of tetragonal Eu:NaGd(WO4)2 crystal 

      Loiko, P. A.; Vilejshikova, E. V.; Mateos, X.; Serres, J. M.; Dashkevich, V. I.; Orlovich, V. A.; Yasukevich, A. S.; Kuleshov, N. V.; Yumashev, K. V.; Grigoriev, S. V.; Vatnik, S. M.; Bagaev, S. N.; Pavlyuk, A. A. (2016)
      We report on growth and detailed spectroscopic study of Eu3ю-doped tetragonal sodium gadolinium double tungstate, Eu:NaGd(WO4)2, a new promising crystal for deep-red lasers. Large-volume crystal doped with 4.9 at.% Eu is grown by Czochralski method along the [001] crystallographic direction. Absorption of Eu3ю ions is studied at room temperature (RT) and at 6 K. For the absorption ...
