Three-level Q-switched laser operation of ytterbium-doped Sr(5)(PO(4))(3)F at 985 nm.
Ytterbium-doped Sr(5)(PO(4))(3)F was successfully lased at 985 nm in quasi-cw mode with a slope efficiency of 74% and an absorbed threshold energy of 18 mJ. Q-switched slope efficiencies of 21% were obtained with a maximum energy of 9.4 mJ in 8.8-ns pulses.
