Abstract
- To the best of our knowledge, the spectroscopic and highly efficient tunable multi-wavelength laser properties of Er<superscript>3+</superscript>,Yb<superscript>3+</superscript>,Pr<superscript>3+</superscript> triple-doped BaLaGa<subscript>3</subscript>O<subscript>7</subscript> crystals are demonstrated for the first time in this study. The maximum output power of 0.81 W at ∼2.7 μm was obtained under the absorbed pump power of 3.53 W with an optical-to-optical conversion efficiency of 22.9%. The slope efficiency is 27.0%. The results demonstrate that the triple-doped crystals with the sensitizer Yb<superscript>3+</superscript> and deactivator Pr<superscript>3+</superscript> can not only enhance the pump efficiency effectively but also suppress the self-terminating "bottleneck" effect of Er<superscript>3+</superscript> so that the laser threshold is reduced and the laser efficiency is improved. The Er<superscript>3+</superscript>,Yb<superscript>3+</superscript>,Pr<superscript>3+</superscript> triple-doped BaLaGa<subscript>3</subscript>O<subscript>7</subscript> crystal is a promising candidate for high-efficiency mid-infrared laser devices.
