Abstract

Buried ridge waveguides are microstructured into a monoclinic potassium double tungstate layer with a composition of KY0.40Gd0.29Lu0.23Tm0.08(WO4)2 grown onto a KY(WO4)2 substrate by liquid-phase epitaxy. When pumping with a Ti:Sapphire laser at 794 nm, the fundamental-mode channel waveguide produces laser emission with a slope efficiency of ~80% and an output power of 1.6 W at 1.84 μm in a resonator with 89% output coupling.
