Abstract

The paper deals with a number o abrioated by an extrusion cladded crystalline fibers. Low-mode fibers have been rabricated after appropriate initial fiber materials and extrusion process parameters were experimentally found. Dierent optical characteristics o such crystalline fibers have been investigated at 10,6 Lm. We discuss the significance o material coatings Lor considerable improvement or optical and. mechanical properties o crystalline core-clad ribers. Fabricated clacided fibers have been coated with dierent protective materials: polymeric and metallic. The erect o such coatings on mechanical properties o core-clad fibers are studied. The et'rect of metal coatings on thelaser damage threshold was estimated ror the continuous regime. We have considered conditions or the ericient second---hainonic generation in core-clad crystalline fibers. At fist time we observed the SHG ot' CO and YAG: Nd lasers in the core-clad crystalline fiber with the cuprous halide core.
