Abstract
Growth and characterization of highly Yb3+-doped KY(WO4)2 thin layers is reported. Liquid phase epitaxial growth and characterization of highly Yb3+-doped (15, 20, and 47.5at%) layers on (010)-oriented, pure KYW substrates is shown. At elevated growth temperatures of 920-925°C a low level of supersaturation was achieved, leading to slower growth rate. This approach resulted in lattice-matched, crack-free layers of thickness ranging from 10 to 50 μm. The doping concentrations in a grown layer were determined by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS).
