title: Evaluation of (4)I(15/2) and (4)I(13/2) Stark-level energies in erbium-doped aluminosilicate glass fibers.
abstract: Spectroscopic measurements of fluorescence and absorption in an erbium-doped fiber permit the evaluation of the Stark-level energies of the (4)I(15/2) and (4)I(13/2) manifolds in Er:glass. The data permit the allocation of the individual laser transitions associated with the room-temperature gain spectrum of erbium-doped fiber amplifiers operating near lambda = 1.53 microm.
