Fluoride glasses: properties, technology and applications
Heavy Metal Fluoride Glasses (HMFG) make a group of specialty glasses that require a dry processing, purity control of starting materials and specific thermal procedures. Numerous glass compositions have been identified in different chemical systems: fluorozirconates, fluoroaluminates and fluoroindates. The most commonly used HMFG is the ZBLAN fluorozirconate glass that exhibits the largest stability against devitrification. By comparison to ZBLAN the IR cut-off wavelength is shorter in AlF3-based glasses and larger in fluoroindates.
Only optical fibres have lead to practical applications that take advantage from IR transmission up to 5 µm and fairly low losses. They concern astronomical and broadband interferometry, remote spectroscopy, thermal sensing, laser power delivery, fibre lasers and optical amplifiers.

Abstract
Heavy Metal Fluoride Glasses (HMFG) make a group of specialty glasses that require a dry processing, purity control of starting materials and specific thermal procedures. Numerous glass compositions have been identified in different chemical systems: fluorozirconates, fluoroaluminates and fluoroindates. The most commonly used HMFG is the ZBLAN fluorozirconate glass that exhibits the largest stability against devitrification. By comparison to ZBLAN the IR cut-off wavelength is shorter in AlF3-based glasses and larger in fluoroindates.
Only optical fibres have lead to practical applications that take advantage from IR transmission up to 5 µm and fairly low losses. They concern astronomical and broadband interferometry, remote spectroscopy, thermal sensing, laser power delivery, fibre lasers and optical amplifiers.
