Abstract
Core-cladding structures constructed for KRS-5 polycrystalline and As/sub 2/S/sub 3/ glass infrared fibers by means of vapor deposition are discussed. In order to obtain high-numerical-aperture fibers, KRS-6 and AsS/sub 3/, respectively, have been used as cladding materials. A CO/sub 2/ laser beam of 15-20 W has been successfully transmitted through the KRS-5 fiber. For the As/sub 2/S/sub 3/ fiber an absorption loss due to Teflon coating has been reduced, and a loss of 0.13 dB/m has been achieved.<>
