Abstract

Single-crystalline $KY_{1-x-y}Gd_{x}Lu_{y}(WO_{4})_{2}$ multi-layers are grown onto undoped $KY(WO_{4})_{2}$ substrates by liquid-phase epitaxy. The lattice matching and refractive-index contrast between layer and substrate is engineered by choosing appropriate amounts of Y, Gd, and Lu. The refractive index at several wavelengths for different compositions and coefficients of the Sellmeier dispersion curves are determined. By microstructuring and subsequent overgrowth an actively ytterbium-doped tapered channel waveguide and a passive planar pump waveguide are created. Laser emission has been demonstrated by diode side pumping with a high-power, multi-mode diode bar. This result offers the potential for significantly increased output powers from channel waveguide laser devices.
