摘　　要：We report on a high-power Ho:YAG single-crystal fiber(SCF)laser inband pumped by a high-brightness Tm-fiber laser at 1908 nm.The Ho:YAG SCF grown by the micro-pulling-down technique exhibits a propagation loss of 0.05±0.005 cm^-1 at 2.09μm.A continuous-wave output power of 35.2 W is achieved with a slope efficiency of 42.7%,which is to the best of our knowledge the highest power ever reported from an SCF-based laser in the 2µm spectral range.
