First demonstration of ~ 5 µm laser action in terbium-doped selenide glass

4.9–5.5 µm laser oscillations were observed in high-purity bulk terbium-doped Ge 36 Ga 5 Se 59 glass pumped by pulsed 2.93 µm Er:YAG laser. This is the first evidence of laser action corresponding to 7 F 5 – 7 F 6 transition of Tb 3+ ions and of mid-infrared lasing in chalcogenide glass host....
