Abstract
A bulk crystal of Er3+:Yb3+:LaMgB5O10 was grown successfully by the top seeded solution growth (TSSG) method. The spectroscopic characterization of this material, including the polarized absorption and fluorescence spectra and the fluorescence decay curve, were recorded. The fluorescence quantum efficiency of the 4I13/2 level of Er3+ ions and the efficiency of energy transfer from Yb3+ to Er3+ ions were estimated. Continuous-wave laser output of 160Â mWÂ at 1567Â nm was realized under the absorbed pump power of 3.1Â W in a hemispherical cavity. When the output coupler transmission was 1.7% the absorbed pump threshold was 1.5Â W and the slope efficiency of the laser was 10.1%. The results show that Er3+:Yb3+:LaMgB5O10 crystal is a promising laser material.
