Abstract
We report the observation of cooperative frequency upconversion in a fluoro indate 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 transfe r from a pair of excited Yb3+ ions. (C) 1998 Elsevier Science B.V.
