Abstract :
Fluoride glasses in the ZrF4-BaF2-RF3 system (R=Gd, Yb) have been investigated as potential low loss materials for achievement of fibres transmitting wavelengths at about 3¿5 ¿m. Optical measurements confirm the interest in such components and PbF2 doping allows substantial refractive index increases, making for feasible doped core glass preforms.
