选用一种新型的环烯烃聚合物COP-E48 R作为银空心玻璃管的介质材料。COP-E48 R/Ag（COP-E48 R/Ag）玻璃空心波导由于在10.6 μm波长处具有较低的消光系数，大大降低了CO2激光在COP-E48 R/Ag玻璃中的传输损耗。通过选择合适的COP膜厚，Er：YAG和CO2激光可以同时或单独低损耗传输。还评估了红色和绿色引导光束的传输特性。
A new kind of cyclic olefin polymer COP-E48R has been selected as the dielectric material for a silver hollow glass tube. Owing to its lower extinction coefficient at the wavelength of 10.6 μm, transmission losses for the CO2laser light has been reduced significantly in the COP-E48R-coated silver (COP-E48R/Ag) hollow glass waveguide. By properly selecting the film thickness of COP, Er:YAG and CO2laser light are shown to be transmitted with low loss simultaneously or independently. Delivery properties of red and green pilot beams were also evaluated.
