LD pumped high-power and efficient CW laser performance of EFG-grown Yb:Lu<sub>2</sub>O<sub>3</sub> and Yb:Sc<sub>2</sub>O<sub>3</sub> crystals
We report the growth, spectral properties, and laser performance of Yb<sup>3+</sup>-doped Sc<sub>2</sub>O<sub>3</sub> and Lu<sub>2</sub>O<sub>3</sub> crystals. The 3 at.% Yb:Sc<sub>2</sub>O<sub>3</sub> crystal achieved a CW laser output power of 15.15 W at 1042 nm, with a slope efficiency of 75% and an optical-to-optical efficiency of 58.6%. The 4 at.% Yb:Lu<sub>2</sub>O<sub>3</sub> crystal achieved a CW laser output power of 9.86 W at 1034 nm, with a slope efficiency of 65% and an optical-to-optical efficiency of 48%. Despite the lower Yb<sup>3+</sup> doping concentration, Yb:Sc<sub>2</sub>O<sub>3</sub> exhibited superior spectral and laser properties compared to Yb:Lu<sub>2</sub>O<sub>3</sub>.
