Abstract

The sesquioxide crystal Yb3+:Lu2O3 is known to be a gain medium with excellent properties for high average power thin-disk lasers due to its low quantum defect of 5.6 % [1] and relatively high thermal conductivity of 12 W/mK [2]. However, the growth of Yb3+:Lu2O3 single crystals is challenging due to its high melting point of 2450 °C [1]. Improvements in ceramic manufacturing techniques as shown in [3] offer poly-crystalline Yb3+:Lu2O3 ceramics with low transmission losses and being free of pores.
