Abstract

We report a high-power laser-diode-array end-pumped 0.3 at. % Nd:GdVO4 continuous-wave laser operating at 1.34 μm. The maximum output power of 13.3 W was obtained at the incident pump power of 49.2 W, giving the corresponding optical conversion efficiency of 27% and the average slope efficiency of 28.5%. The thermal focal length of the Nd:GdVO4 crystal under the pump power from 15.3 to 50 W was measured experimentally.
