Industrial, Medical and Military Applications of Fluoride and Chalcogenide Glass Fibers

Owing to the low phonon energies, fluoride and chalcogenide glasses have wide optical transparent windows extending from the visible to mid- or even far-infrared region. They have widely used in the applications of infrared laser power delivery, image transmission, fiber laser generation and etc. On the other hand, infrared fiber devices have also been paid much attention because they are fundamental elements for developing infrared mid-lasers. This chapter will discuss the above applications and devices.
