High-quality crystalline KY(WO 4 ) 2 :Yb 3+ layers codoped with large concentrations of optically inert Gd 3+ and Lu 3+ ions were grown by liquid phase epitaxy. Continuous-wave laser operation in a planar waveguide configuration was observed at 1025 nm. For 23% output coupling, a maximum output powe
