摘要

Tm3+-doped 2-μm lasers benefit many applications such as atmospheric sensing,medical treatment,and spectroscopy [1-3].Therefore,in the past two decades,both continuous-wave (CW) and pulse operations have been widely researched in Tm3+-doped bulk materials and fibers [4-7].Among bulk materials,both crystalline and ceramic Tm3+-doped yttrium aluminum garnets (Tm:YAG) are preferred candidates for 2-μm laser applications,especially for high-power and high-energy laser operations owing to their remarkable thermo-mechanical properties.
