摘要：
Enhanced 2.85 mu m and 2.0 mu m emission from Er3+/Yb3+/Ho3+ triple doped germanate glass have been obtained under 980 nm laser diode excitation. The emission's spectroscopic property and the reasonable energy transfer mechanism were studied. Based on the absorption spectra, the Judd-Ofelt parameters, spontaneous emission probability, and consequently the absorption and emission cross sections were calculated and compared with those of other glasses. In addition, the measured decay lifetime of I-5(7) of Ho3+ was measured to be about 7.583 ms, which is beneficial for 2.0 mu m lasers. The results indicate that the Er3+/Yb3+/Ho3+ triply doped germanate glass has potential application in mid-infrared lasers.
