    • Microchip laser operation of Tm,Ho:KLu(WO4)2 crystal 

      Loiko, P.; Serres, J. M.; Mateos, X.; Yumashev, K.; Kuleshov, N.; Petrov, V.; Griebner, U.; Aguilo, M.; Diaz, F. (2014)
      A microchip laser is realized on the basis of a monoclinic Tm,Ho-codoped KLu(WO4)2 crystal cut for light propagation along the Ng optical indicatrix axis. This crystal cut provides positive thermal lens with extremely weak astigmatism, S/M = 4%. High sensitivity factors, M = dD/dPabs, of 24.9 and 24.1 m−1/W for the mg- and pg- tangential planes are calculated with respect to the ...

    • Passively Q-Switched Thulium Microchip Laser 

      Gaponenko, M.; Kuleshov, N.; Südmeyer, T. (2016)
      We present the first passively Q-switched thulium microchip laser. The diode-pumped laser incorporates a Tm:KYW gain medium and an InGaAs semiconductor saturable absorber mirror. The laser emits pulses with a duration of 2.4 ns at a repetition rate of 1.2 MHz with an average output power of 130 mW at a wavelength of 1905 nm. It operates in a fundamental TEM00 mode with M2 < 1.1. ...
