For the sake of studying thermal conduction characteristic of different doped YAG and GGG laser crystals,the thermal conductivities of different doped YAG and GGG laser crystal generated from 273K to 393K were measured by making use of instantaneous measuring method,and the temperature field model of the experimental sample was established,the function of thermal conductivity to the temperature was educed.The obtained conductivity/temperature curves almost conformed with the experimental results.The experimental results make clear that the thermal conductivity of the laser crystal decline to the temperature,the thermal conductivity of YAG laser crystal declines after doped with Yb ions,the thermal conductivity of the GGG laser crystal declines with the rising of the doped Nd ions concentration.Finally,the experimental results were theoretically explained.
