报道了一种高效率的多晶Tm：YAG陶瓷激光器，该激光器由1617 nm的Er：YAG激光器带内泵浦。4.0和6.0 at.%的激光特性对Tm（3+）掺杂的YAG陶瓷进行了研究和比较。当输出耦合器的透过率为10%时，在12.8W的泵浦功率下，在2015nm处获得了7.3W的最大输出功率，对应于入射泵浦功率的斜率效率为62.3%。
We report on a highly efficient polycrystalline Tm:YAG ceramic laser in-band pumped by an Er:YAG laser at 1617 nm. Lasing characteristics of 4.0 and 6.0 at.%Tm(3+)-doped YAG ceramics were investigated and compared. With an output coupler of 10% transmission, a maximum output power of 7.3 W was obtained at 2015 nm under 12.8 W of incident pump power, corresponding to a slope efficiency with respect to incident pump power of 62.3%.
