Abstract :
Yb:YAG single crystals were grown by the Czochralski method. Thermal properties like thermal diffusivity, conductivity and expansion of various Yb3+ concentration are studied from 50 to 500 °C. The effects of temperature and Yb3+ concentration on the thermal properties of Yb:YAG crystals are discussed. The deterioration of thermal properties of highly doped Yb:YAG is possibly due to the structural distortion caused by the Yb3+ ions.
