Abstract
Resonance-fluorescence-line-narrowing studies have been performed on a representative group of Er3+ -doped glasses for excitation in both the 1530 and 980-nm bands at 4.2, 77, 200, and 300 K. Fluorozirconate, fluorophosphate, phosphate, silicate, Ge/P-doped and A1/P-doped silica preforms, and Al/P-doped and Ge-doped fibers were examined. At 77 K the homogeneous linewidths were found to be relatively insensitive to composition. In particular, they vary from 1.4 to 1.8 cm-1 for the different hosts using excitation at 1531 nm. At 300 K weak resonant features were observed in most samples, consistent with a small inhomogeneous contribution to a predominantly homogeneous fluorescence emission.
