Type: article
Abstract: We report the growth, spectral properties, and laser performance of Yb 3+ -doped Sc 2 O 3 and Lu 2 O 3 crystals. The 3 at.% Yb:Sc 2 O 3 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 2 O 3 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 3+ doping concentration, Yb:Sc 2 O 3 exhibited superior spectral and laser properties compared to Yb:Lu 2 O 3 .
