摘　　要：对中频感应提拉法生长的不同掺杂浓度的Yb∶YAG晶体的比热和导热性能进行了测试。表明Yb3 +离子的掺杂导致了晶体比热的减小和晶体导热性能的降低 ,并认为导热性能降低是Yb3Yb∶YAG laser crystals are grown by the Czochralski technique. The specific heat and thermal diffusivity data of Yb∶YAG are measured. It shows that the doping of Yb 3+ ions leads to the decrease of specific heat and thermal diffusivity, especially when the doping concentration is high. And the decrease of the latter is regard as the result of lattice deformation caused by the doped Yb 3+ ions.
