Abstract

Fluorotellurite based glasses have been investigated for numerous optical applications such as lasers, fibre optic, waveguide, and Raman gain devices. The fluorotellurite materials exhibit unique high linear and nonlinear refractive indices ( please add data), extended UV- and IR transparency (0.35 to 5.0µm). Above all the glass host promotes the retention of large concentrations of RE³⁺-ions in an environment of depleted OH-ions which is advantageous from the point of view of enhanced spectroscopic properties for light amplification in visible and near-IR.
