摘要：

An Er:Yb:Sr3Lu2(BO3)(4) crystal was grown by the Czochralski method. Spectral properties of the crystal were investigated, including the absorption and fluorescence spectra and the fluorescence decay. The fluorescence quantum efficiency of the I-4(13/2) level of Er3+ ions and efficiency of energy transfer from Yb3+ to Er3+ ions were calculated. End-pumped by a diode laser at 970 nm in a hemispherical cavity, laser performance of a 1.08-mm-thick Z-cut Er:Yb:Sr3Lu2(BO3)(4) crystal was investigated. Compared with those of Er: Yb: Sr3Y2(BO3)(4) crystal obtained in the same experimental condition, lower threshold, higher maximum output power, and comparable slope efficiency were achieved in the Er:Yb:Sr3Lu2(BO3)(4) crystal.
