辐射输送是各种应用所必需的，主要是在医学或工业中。由于传输红外、紫外或强辐射的需要，由于标准玻璃纤维会产生严重的损耗，因此研究了通过中空波导传输红外、紫外或强辐射。我们的特殊波导是基于熔融石英玻璃毛细管与内部银层和介电膜（环烯烃聚合物（COP））。设计并制作了Er：YAG（2.94 μm）、Dy：PbGa_2S_4（4.3 μm）和Fe：ZnSe（4.45 μm）三种激光器作为中红外光源。表征了COP/Ag空心玻璃波导传输3 - 5 μm辐射的空间光束轮廓和传输能力。
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.
