摘要

Absorption and fluorescence spectra of Nd↑(3-) were measured m 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 ↑(4)F↓(2/3) → ↑(4)I↓(11/2) transition of Nd↑(3-). Raman spectra were studied to clarify the maximum phonon energies of the glasses. The fluorescence of the ↑(1)G↓(4)→↑(3)H↓(5) transition of P↑(3-) 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. #1997 Optical Society of America
