Glasses based on fluorides of metals of the I–IV groups: Synthesis, properties, and application

Authors:

Abstract
A review of the current studies on the synthesis, glass formation, structure, and optical properties of fluoride glasses in various glass-forming systems is presented. With a view to form and select active optical media for broad spectrum lasers, extensive studies are conducted to clarify the fluorescence mechanisms in fluoride glasses of various compositions doped with REE activators. Studies on obtainment of REE-activated fluoride transparent glass ceramics are discussed. Promising directions of practical application of such materials in optics and laser technology are shown.
