In this Letter, for the first time, to the best of our knowledge, a pulse and CW laser based on an Er-doped GdGaAlO (Er:GGAG) active medium emitting laser radiation at 2.8 μm are presented. With the longitudinal diode pumping, the maximal output energy of 4.9 mJ and slope efficiency of 13.5% in the pulse regime were reached. Using the birefringent MgF plate, the line tunability of Er:GGAG at several spectral bands of 2800-2822 nm, 2829-2891 nm, and 2917-2942 nm were obtained.
在这封信件中，据我们所知，首次展示了基于掺铒镓铝石榴石（Er:GGAG）的脉冲和连续波激光，其发射波长为 2.8μm 的激光辐射。采用纵向二极管泵浦，在脉冲模式下获得了最大输出能量为 4.9mJ 和斜率效率为 13.5%的结果。利用双折射 MgF 板，获得了 Er:GGAG 在 2800-2822nm、2829-2891nm 和 2917-2942nm 几个光谱带的线调谐。
