    High-quality monoclinic $KY(WO_{4})_{2}$ optical waveguides were grown by liquid-phase epitaxy, and laser operation of an Yb-doped $KY(WO_{4})_{2}$ waveguide was demonstrated for the first time to our knowledge. Continuous-wave laser emission near 1 μm was achieved with both surface and buried planar waveguides. An output power of 290 mW was obtained in the fundamental mode and the slope efficiency was above 80%.
