采用双程泵浦微型激光器结构研究了重掺杂Yb:YAG陶瓷的激光性能。对于掺杂20at.%镱离子的1毫米厚YAG陶瓷，已实现52%的斜率效率和48%的光 - 光效率。在不同的腔内激光强度下，研究了Yb:YAG陶瓷和单晶激光器的激光光谱。与具有相同Yb³⁺离子激光工作物质的单晶相比，重掺杂Yb:YAG陶瓷更适用于薄盘激光器。
Laser performance of heavy-doped Yb:YAG ceramics was investigated using a two-pass pumping miniature laser configuration. Slope efficiency of 52% and optical-to-optical efficiency of 48% have been achieved for 1-mm-thick YAG ceramic doped with 20 at.% ytterbium ions. Laser spectra of Yb:YAG ceramic and single-crystal lasers were addressed under different intracavity laser intensities. Heavy-doped Yb:YAG ceramic is more suitable for a thin disk laser than a single-crystal with the same Yb(3+)-ion lasants.
