The absorption and emission cross sections of YbYAG crystal are determined using Reciprocity method. Temperature dependence of 941nm absorption cross section and 1031nm emission cross section is extracted in the range of 300450K. According to our experimental results, an exponential temperature dependence between 300K and 450K is acquired for the 1031nm peak emission cross section and also for 941nm peak absorption cross section of YbYAG crystal. These results could be used for simulation and design of high power highly doped YbYAG thin disk lasers.</abstract> <index>Open Science Index 63, 2012</index> </article>
