Abstract
An application to transitions involving thermalized states of a procedure b ased on the McCumber theory to determine emission and absorption cross sect ions in waveguides from transversal fluorescence spectra is presented. The procedure is tested in Er-doped Ti:LiNbO3 waveguides to provide accurate cr oss-section values for the recently attractive 550-nm band. We also study t he excited-state absorption transition around 860 nm and present, to our kn owledge, the first published cross-section values for this transition.
