HIGH POWER OPTICAL FIBER

摘要

The fibre has pref. an infrar-red transmissive core (1) of a thallium, alkali or silver halide crystal or a chalcogenide glass. The core circumference is coated with a layer (2) of lead fluoride and a second layer (3) of germanium. A multiple lamination consists of alternate layers of lead fluoride and germanium or silver chloride or silver bromide. Only the vicinity of each of the incident and exit portions of the optical fibre need be coated with the alternately laminated multi-layer film.
