Abstract

High-quality monoclinic KY(WO4)2 optical waveguides were grown by liquid-phase epitaxy, and laser operation of an Yb-doped KY(WO4)2 waveguide was demonstrated for the first time to our knowledge. Continuous-wave laser emission near 1μm was achieved with both surface and buried planar waveguides. An output power of 290mW was obtained in the fundamental mode and the slope efficiency was above 80%.
