Crystal growth, spectral properties, and 2.3 µm continuous-wave laser operation of Tm:YScO<sub>3</sub> and Tm:LuScO<sub>3</sub> crystals
Tm<sup>3+</sup>-doped sesquioxides, Tm:YScO<sub>3</sub>, and Tm:LuScO<sub>3</sub> crystals, were successfully fabricated by using a laser floating zone method. For the first time, continuous-wave laser operation at 2.3 µm on the <sup>3</sup>H<sub>4</sub> → <sup>3</sup>H<sub>5</sub> Tm<sup>3+</sup> transition of the two crystals was reported. Pumped by a 793 nm fiber-coupled laser diode, the Tm:YScO<sub>3</sub> and Tm:LuScO<sub>3</sub> lasers generated the maximum continuous-wave laser output power of 665 mW and 872 mW at 2.3 µm with a slope efficiency of 9.5% and 16.1%, respectively.
