摘要：
We report a high-power laser-diode-array end-pumped 0.3 at.% Nd: GdVO4 continuous-wave laser operating at 1.34 mum. The maximum output power of 13.3W 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.
