摘要：
Mid-infrared fiber lasers operating at 3 μm bands have attracted considerable attention due to their potential applications in medicine，environmental monitoring，military defense，etc. One of the key foundations to achieve 3 μm mid-infrared fiber laser is the gain medium made by efficient and stable glass host materials with low phonon energy. In this study，novel Er3+-doped Al2O3-CaO-ZnO glasses were synthesized by melt-quenching method. Properties of thermodynamic，structure，transmission wavelength range，and mid-infrared emission were studied by thermal analysis，Raman spectra，transmission spectra，and photoluminescence spectra. The results showed that Al2O3-CaO-ZnO glasses possess a high glass transition temperature（~750 ℃），low phonon energy（~780 cm−1），and wide transmission wavelength range（0. 5−5 μm）. Besides，intense 2. 7 μm emissions originating from Er3+：4I11/2→4I13/2 transition were observed in glass under 980 nm laser diode excitation. Our results indicate that Al2O3-CaO-ZnO glasses could be a potential host material for mid-infrared laser. © 2024 Editorial Office of Chinese Optics. All rights reserved.
