We present a simplified approach to evaluate the thermal conductivity of insulating crystals, taking into account chemical and structural properties. We complete the thermal conductivity evaluation in the case of point defects encountered in luminescent materials. Thermal conductivity coefficients have been determined by photothermal experiments and are in good agreement with the predicted values in Yb:Y[sub 3]Al[sub 5]O[sub 12] and Yb:Gd[sub 3]Ga[sub 5]O[sub 12] solid-state lasers. © 2003 American Institute of Physics.
