Description

Radiation delivery is required for various applications—mainly in medicine or industry. Due to the necessity of delivering IR, UV or powerful radiation, its transfer by hollow waveguides was investigated because standard glass fibers cause serious losses. Our special waveguide was based on a fused silica glass capillary tube with an inner silver layer and dielectric film (cyclic olefin polymer (COP)). Three lasers were designed and constructed as mid-infrared sources, namely Er:YAG (2.94 μm), Dy: PbGa2S4 (4.3 μm) and Fe:ZnSe (4.45 μm). The delivered spatial beam profile and transfer capability of 3−5 μm radiation by the COP/Ag hollow glass waveguide were characterized. (letter)
