文摘

An Er³⁺-doped oxyfluorogallate glass is investigated as a laser material with 2.7 µm emission. The 2.7 µm emission properties of the Er³⁺-doped oxyfluorogallate glasses are obtained using a 980 nm laser diode and their spontaneous transition probabilities and branching ratios are predicted using Judd–Ofelt theory. The maximum value of emission cross-section of Er³⁺ around 2.7 µm reached 1.32×10⁻²⁰ cm², which suggests a very promising application of oxyfluorogallate glass for efficient 2.7 µm solid-state laser system.
