摘要：
An Er:Yb:GdAl3(BO3)(4) crystal was grown and room-temperature polarized absorption, emission, and 3 gain spectra were investigated. Fluorescence decay curves of Er3+ at 1530 run and Yb3+ at 1040 am in the crystal were measured. Efficient laser operation of Er:Yb:GdAl3(BO3)(4) crystal at 1.5-1.6 mu m was realized. Quasi-continuous-wave output powers of 1.8 W with slope efficiency of 19% and 0.78 W with slope efficiency of 14% were achieved in diode-pumped c-cut and a-cut crystals, respectively. The output spectrum and polarization of Er:Yb:GdAl3(BO3)(4) laser were also investigated.
