Abstract

Lead germanate glass of good optical quality was synthesized by fusion of components and subsequently casting in air atmosphere. The absorption spectrum from near-infrared to visible was obtained and the Judd-Offelt parameters were determined from the absorption bands. Emission cross section at 1.53 μm and the excited state lifetime were determined from the measurements. Pumping with 976 nm beam from a LD pump resulted in the emissions centered at 547 and 659 nm due to the ⁴S_3/2→⁴I_15/2 and ⁴F_9/2→⁴I_15/2 transitions in Er³⁺ ions, respectively. Theoretical and experimental lifetimes were determined and the results were discussed.
