    Abstract: Halide fibres are protected by coatings up to 2µm thick of chalcogenide glasses, eg glasses based on compounds of S, Se or Te with Ge or As. The coatings are deposited on the fibre preform by ion deposition sputtering. Preferably the preform is etched by directing a stream of inert ions at it. Most suitably the etching immediately precedes the coating.

    Abstract translation: 卤化物纤维受到厚达2微米厚的硫族化物玻璃的涂层保护,例如基于S,Se或Te与Ge或As的化合物的玻璃。 通过离子沉积溅射将涂层沉积在纤维预制件上。 优选地,通过在其上引导惰性离子流来蚀刻预制件。 最适当地,蚀刻紧接在涂层之前。
