Description/Abstract
Absorption and fluorescence spectra of Nd3+ were measured in potassium tantalum gallate, lead bismuth gallate (PBG), fluorozirconate (ZBLAN), and Ge-Ga-S glasses. A Judd-Ofelt analysis was performed to determine the spontaneous emission probability and stimulated emission cross section of the 4F(3/2) to 4I(11/2) transition of Nd3+. Raman spectra were studied to clarify the maximum phonon energies of the glasses. The fluorescence of the 1G4 to 3H5 transition of Pr3+ in a dehydrated PBG glass was observed for the first time to our knowledge. The PBG glass has a higher quantum efficiency than that of ZBLAN glass based on the Judd-Ofelt analysis
