N2 - In Er3+/Yb3+ codoped Na2O-ZnO-PbO-GeO 2-TeO2 (NZPGT) glass fiber, a clear and compact green upconversion amplified spontaneous emission (ASE) trace is observed, and the NZPGT glasses are proved to be a desirable candidate in fabricating low-phonon energy fiber. Intense green upconversion luminescence of Er3+, balanced green and red upconversion emissions of Ho3+, and dominant three-photon blue upconversion fluorescence of Tm3+ have been represented. By varying the excitation power of 974nm wavelength laser diode, a series of green and white fluorescences have been achieved in Tm 3+/Er3+/Yb3+ and Tm3+/Ho 3+/Yb3+ triply doped glass systems, respectively. These results reveal that high-intensity blue, green, and white upconversion ASE fluorescences, which can be adopted for lighting in minimally invasive photodynamic therapy and minimally invasive surgery, are reasonable to be expected in rare-earth doped NZPGT glass fibers. © 2010 Optical Society of America.
