Abstract

In this Letter, for the first time, to the best of our knowledge, a pulse and CW laser based on an Er-doped Gd₃Ga_2.7Al_2.3O₁₂ (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 MgF₂ plate, the line tunability of Er:GGAG at several spectral bands of 2800-2822 nm, 2829-2891 nm, and 2917-2942 nm were obtained.
