    • Compact passively Q-switched diode-pumped Tm:KY(WO4)2 laser with 8 ns/30 μJ pulses 

      Gaponenko, M. S.; Onushchenko, A. A.; Kisel, V. E.; Malyarevich, A. M.; Yumashev, K. V. (2012)
      A compact diode-pumped solid-state Tm:KY(WO4)2 laser with cavity length of 1 cm passively Q-switched with a PbS-quantum-dot-based saturable absorber is presented. The laser operates at the wavelength of 1.94 ¹m and produces pulses with duration of 8 ns and energy of 30 ¹J at the repetition rate up to 4.2 kHz. The maximum output power of 120 mW is achieved at incident pump power ...

    • Efficient diode-pumped Tm:KYW 1.9-μm microchip laser with 1 W cw output power 

      Gaponenko, M. S.; Kuleshov, N. V.; Südmeyer, T. (Optical Society of America, 2014)
      We report on a diode-pumped Tm:KYW microchip laser generating 1 W continuous-wave output power. The laser operates at a wavelength of 1.94 μm in the fundamental TEM00 mode with 71% slope efficiency relative to the absorbed pump radiation and 59% slope efficiency relative to the incident pump radiation. The optical-to-optical laser efficiency is 43%.

    • Passive mode locking of 2.09 μm Cr,Tm,Ho:Y3Sc2Al3O12laser using PbS quantum-dot-doped glass 

      Denisov, I. A.; Skoptsov, N. A.; Gaponenko, M. S.; Malyarevich, A. M.; Yumashev, K. V.; Lipovskii, A. A. (Optical Society of America, 2009)
      Passive Q-switched mode locking of a 2.09 μm flashlamp-pumped Cr3+,Tm3+,Ho3+:Y3Sc2Al3O12 laser by use of a phosphate glass doped with PbS quantum dots of 5 nm in radius was demonstrated. Mode-locked pulses of 290 ps in duration and up to 0.5 mJ in energy were registered.
