Abstract:	Laser operation at 1025 nm with 82.3% slope efficiency and 195 mW output power for 23% outcoupling is reported for KY(WO4)2:Yb3+ planar waveguides, co-doped with optically inert Gd3+ and Lu3+ ions. Codoping enhances the refractive index contrast, improves light confinement, and reduces the threshold to 18 mW (1.7% outcoupling).
