Highly efficient tunable multi-wavelength laser of Er3+, Yb3+, Pr3+ triple-doped BaLaGa3O7 crystal at ~2.7 µm To the best of our knowledge, the spectroscopic and the highly efficient tunable multi-wavelength laser properties of Er3+, Yb3+, Pr3+ triple-doped BaLaGa3O7 crystals are demonstrated for the first time. The maximum output power of 0.81 W at ~2.7 µm has been obtained under the absorbed pump power of 3.53 W with the optical-to-optical conversion efficiency of 22.9%.
