    Continuous wave (CW) and Q-switched diode-pumped laser operation of Yb3+:NaLa(MoO4)2 single crystal was to our knowledge, demonstrated for the first time. A CW output power of 220 mW and slope efficiency of 46% were obtained. Q-switched laser operation was achieved with a pulse duration of 60 ns average output power of 70mW and slope efficiency of 22%

  • Ho:KLuW microchip laser intracavity pumped by a diode-pumped Tm:KLuW laser 

    Serres, J. M.; Loiko, P. A.; Mateos, X.; Yumashev, K. V.; Kuleshov, N. V.; Petrov, V.; Griebner, U.; Aguiló, M.; Díaz, F. (Springer, 2015)
    A compact intracavity-pumped microchip Ho laser is realized using stacked Tm:KLuW/Ho:KLuW crystals pumped by a laser diode at 805 nm; both crystals are cut for light propagation along the Ng optical indicatrix axis and emit with polarization along the Nm axis. Maximum CW output power of 285 mW is achieved at a wavelength of 2080 nm for 5.6 W absorbed pump power in the Tm:KLuW ...

  • Passive Q-switching of Yb bulk lasers by a graphene saturable absorber 

    Loiko, P. A.; Serres, J. M.; Mateos, X.; Liu, G.; Zhang, H.; Yasukevich, A. S.; Yumashev, K. V.; Petrov, V.; Griebner, U.; Aguilo, M.; Diaz, F. (Springer, 2016)
    Compact Yb:KLu(WO4)2 and Yb:LuVO4 lasers diode-pumped at 978 nm are passively Q-switched by a single-layer graphene saturable absorber. The Yb:KLu(WO4)2 laser generated 165 ns/0.49 μJ pulses at 1030 nm with 170 mW average output power and 12 % slope efficiency. With the Yb:LuVO4 laser, 152 ns/0.83 μJ pulses were achieved. The output power reached 300 mW at 1024 nm, and the slope ...

  • Thermo-optic properties of Yb:Lu2O3 single crystals 

    Loiko, P. A.; Yumashev, K. V.; Schödel, R.; Peltz, M.; Liebald, C.; Mateos, X.; Deppe, B. (Springer, 2015)
    A detailed study of thermo-optic properties of 1.5 at.% Yb:Lu2O3 single crystal is performed. Thermo-optic dispersion formulas are derived for dn/dT coefficient and thermal coefficient of the optical path. At the wavelength of 1.03 μm, dn/dT = 5.8 × 10−6 K−1. High-precision temperature-dependent measurements of the thermal expansion coefficient α are performed. At the room ...
