Epitaxial monoclinic double tungstate laser crystals were grown with high crystalline quality. Based on these Yb-doped composites, laser operation was demonstrated. Continuous-wave laser emission of a Yb:KYW/KYW crystal was achieved at 1030 nm. The 25-μm-thin Yb:KYW layer was pumped at wavelengths near 980 nm by a Ti:sapphire laser. A maximum output power of 40 mW was obtained at room temperature.

    An alternative approach is presented for the plasma-assisted molecular beam epitaxy of high-quality GaN. Under N-rich growth conditions, an unexpected layer-by-layer growth mode was found for a wide range of growth temperatures in the GaN thermal decomposition regime (>750 °C). Consequently,...
