Abstract

High purity is a fundamental requirement to enable laser-cooling-grade materials. The vertical Bridgman method is well suited for crystal growth on the few-grams scale, which is compatible with purification techniques that aim to exceed the typical 99.999% to 99.9999% purity of commercial precursor materials. Here, we present advances in the Bridgman crystal growth of cooling-grade LLF:Yb single crystals in a radio-frequency heated furnace. Optical spectroscopy, cooling efficiency, and power cooling characterization are reported. COMSOL simulations were used to investigate the thermal gradient inside the crucible as the crystal growth proceeds.
