Beschreibung:
  • The use of Yb3+ as a sensitizer for Er3+ doped laser materials is a common technique because of the high Yb3+ absorption cross sections. Energy transfer processes from Yb3+ to Er3+ in Sc2O3 are studied by two different methods. Transfer parameters describing the interactions between Er3+ and Yb3+ ions are obtained on the one hand from the ratio of emitted photons around 1.55 μm by Er3+ ions and around 1 μm by Yb3+ ions at cw excitation of Yb3+, on the other hand by lifetime measurements of Yb3+ ions in the codoped samples. Laser experiments are performed to study the suitability of Er3+,Yb3+:Sc2O3 as a laser material. Comparisons with energy transfer in Er3+,Yb3+:glass are made. © 2009 Elsevier B.V.
