The eye-safe Thulium (Tm3+) laser emission at ∼2 μm, based on the 3F4 → 3H6 transition, is of interest for remote sensing and medicine. Monoclinic double tungstates are known as excellent hosts for Tm + ions allowing for efficient lasers at ∼1.94 μm [1]. However, they suffer irom low thermal conductivity (∼3 W/mK) limiting the power scaling. Recently, another monoclinic tungstate crystal with a wolframite structure, MgWO4 which exhibits much better thermal properties has been proposed for RE3+ doping [2]. In the present work, we report on efficient and compact Tm:MgWO4 lasers at >2 μm.
