Using high-spatial and -spectral brightness laser diodes, a resonantly pumped high-power continuous-wave (CW) Er3+:YAG laser with up to 9 W of output power could be realized. Due to the lower upconversion loss in the 0.5% Er3+-doped crystal, intrinsic efficiencies of up to 64.3% and an optimum outcoupling of ∼20% were found. The output power was compared to quasi-three-level theory with good agreement. In an optimized cavity design a mode fill efficiency of ∼95% was achieved.
