Abstract

We report the highly efficient continuous-wave diode-pumped laser operation of Er, Yb:GdAl3 BO3 4 crystal. Absorption and stimulated emission spectra, emission lifetimes, and efficiencies of energy transfer from Yb3 to Er3 ions were determined. A maximal output power of 780 mWwas obtained at 1531 nm at absorbed pump power of 4 W with slope efficiency of 26%.
