Abstract: we report the last experimental results obtained measuring the thermal lens effect in Yb(1at.%):Lu2O3, Yb(1at.%):Sc3O3, Yb(10at.%):LuAG and Yb(10at.%):YAG ceramics. The experimental set-up apparatus using a Shack-Hartmann wavefront sensor allows the comparison of the thermal lens obtained under lasing and non lasing conditions, in order to highlight differences in the thermal loading.
