    • Graphene Q-Switched Compact Yb: YAG Laser 

      Serres, J. M.; Jambunathan, V.; Mateos, X.; Loiko, P.; Lucianetti, A.; Mocek, T.; Yumashev, K.; Petrov, V.; Griebner, U.; Aguilo, M.; Diaz, F. (2015)
      We describe a compact Yb: YAG laser Q-switched by a graphene-based saturable absorber and pumped by a laser diode at 932 or 969 nm. The compact laser generates a maximum average output power value of 185 mW at 1032 nm with a slope efficiency value of 12%. The shortest duration of the Q-switched pulse achieved is 228 ns at a repetition frequency of 285 kHz. The maximum pulse energy ...

    • Passive Q-switching of a Tm,Ho:KLu(WO4)2 microchip laser by a Cr:ZnS saturable absorber 

      Serres, Y. M.; Loiko, P. A.; Mateos, X.; Jambunathan, V.; Yasukevich, A. S.; Yumashev, K. V.; Petrov, V.; Griebner, U.; Aguilo, M.; Diaz, F. (Optical Society of America, 2016)
      A diode-pumped Tm;Ho:KLu WO42 microchip laser passively Q-switched with a Cr:ZnS saturable absorber generated an average output power of 131 mW at 2063.6 nm with a slope efficiency of 11% and a Q-switching conversion efficiency of 58%. The pulse characteristics were 14 ns∕9 μJ at a pulse repetition frequency of 14.5 kHz. With higher modulation depth of the saturable absorber, 9 ...
