Intense 2.7 μm emission derived from modified Er3+ doped germanate glass was reported. Raman spectrum analysis was carried out to grasp glass structure. Based on the absorption spectrum, the Judd-Ofelt parameters and radiative properties were calculated originated from Judd-Ofelt theory. 2.7 μm emission characteristics, stark splitting features and energy transfer processes upon excitation of a conventional 808 nm or 980 nm laser diode were carefully investigated. The prepared glass possesses high spontaneous transition probability (34.28 s-1), large calculated emission cross section (13 × 10-21 cm2) and gain coefficient (5.4 cm 1) for the 4I11/2 → 4I13/2 transition. These results indicate that Er3+ doped germanate glass has potential applications in mid-infrared lasers and amplifiers.
