Abstract :
It is the first time that we report continuous-wave (cw) lasing of uncooled Yb:NaLaW, the second disordered crystal of that type after the isostructural Yb:NaGd(WO4)2 or Yb:NaGdW whose laser performance is described. The interest in such Yb-doped tetragonal sodium double tungstates is due to their potential to ensure larger bandwidths (supporting sub-100 fs pulses) in mode-locked lasers in comparison to the monoclinic potassium double tungstates Yb:NaGd(WO4)2, Yb:KY(WO4)2 and Yb:KLu(WO4)2.
