Abstract

Excited-state absorption spectra of erbium and thulium doped gallium lanthanum sulphide glasses reveal transitions whose final 4f states do not appear in the ground state absorption spectra due to resonance with the fundamental absorption of the glass host. The results give direct evidence for the model of isolated rare earth ions with highly shielded 4f levels showing no noticeable interaction with the host material despite resonance. Only the energy splitting of the 4f levels is relevant for energy transfer processes between rare-earth ions and the host material whereas the absolute energetic position is unimportant.
