Spectroscopy and efficient laser operation near 1.95 μm of Tm3+ in disordered NaLu(WO4)2

Continuous wave and tunable laser operation at room temperature is demonstrated with single crystals of Tm-doped NaLu(WO4)2. Under Ti:sapphire laser pumping and tuning by an intracavity Lyot filter, the Tm3+ emission extended from 1799 to 2026 nm. The maximum output power exceeded 0.5 W and the maxi...
