Abstract :
The conversion of infra-red to visible light has been studied in a series of fluoride glasses doped with YbF3 and ErF3. The frequency up-conversion efficiency of these bulk materials is four orders of magnitude greater than that observed in doped oxide glasses, and compares very favourably with results obtained for Yb3+/Er3+-containing crystals.
