摘要：

An Er:Yb:Sr3Y2(BO3)(4) crystal doped with 0.9 at.% Er3+ and 18.6 at.% Yb3+ ions was grown by the Czochralski method. End-pumped by diode laser at 970 nm in a hemispherical cavity, 1.3 W quasi-cw laser output around 1.56 mu m was achieved in a 1.1-mm-thick Z-cut Er:Yb:Sr3Y2(BO3)(4) crystal when the transmission of output coupler is 1.5%. The absorbed pump threshold and slop efficiency of the laser are 4.26 W and 20%, respectively. This crystal has flat and broad gain curve peaked around 1.56 mu m, which shows that it is also a potential gain medium for tunable and short pulse lasers. (C) 2008 Optical Society of America
