Absorption spectra of lanthanideions in perfluorinated (PF) plastic solution were measured, and the radiative properties were determined by the absorption measurements and the Judd- Ofelt theory. Fluorescence spectrum of Nd³⁺ in PF plastic solution from 900 nm to 1350 nm, pumped at 580 nm, were measured for the first time. Lasing properties of a rhodamine 6G-doped graded-index plastic optical fiber laser (GI-POFL) and a rod laser were investigated. All measurements demonstrated the superior performance of the GI-POFL. This paper also discusses the lasing properties on the basis of near-field pattern measurements.
