Abstract
Thermal conductivity values of laser material Yb3+:CaGdAlO4 (CALGO) with various doping rate in Yb3+ were measured experimentally and compared to predictive values obtained by modelling. The observed variation of the thermal conductivity with the Yb3+ content could be explained by changing the ratio of site substitution Gd3+/Ca2+ by Yb3+. The influence of velocity sound and interionic distance values on thermal conductivity was also studied. Finally, laser results obtained with a 2%Yb:CALGO thin-disk were presented, strengthening the potential of Yb:CALGO for high power laser and ultra-short pulses generation.
