Abstract: A novel trigonal ordered langasite-type silicate crystal, Yb3+: Ca3NbGa3Si2O14 (Yb: CNGS), is characterized with respect to absorption and stimulated-emission crosssections as well as Raman spectra using polarized light. Thanks to its excellent thermomechanical properties, highly-efficient multi-watt lasing is demonstrated. A compact a-cut 5 at.% Yb: CNGS crystal diode-pumped at 978 nm generated a maximum output power of 7.27 W at 1062-1068 nm with a slope efficiency of 78%. These values represent record parameters for similar to 1 mu m lasers based on langasite-type crystals. The very broad and smooth gain cross sections of Yb: CNGS are attractive for ultrashort pulse and broadly tunable lasers at similar to 1 mu m. (C) 2017 Optical Society of America
