Resumo

We report the observation of cooperative frequency upconversion in a fluoroindate glass. The experiments were performed by exciting Yb3+-Tb3+ codoped samples with an infrared diode laser. The process is monitored through the green fluorescence emitted by Tb3+ ions due to a cooperative energy transfer from a pair of excited Yb3+ ions. © 1998 Elsevier Science B.V. All rights reserved.
