Paper Abstract

Cyclic Olefin Polymer (COP)-coated silver hollow glass waveguides were proposed and fabricated for IR laser light transmission such as Er:YAG, CO, and CO2 lasers. Silver mirror reaction and liquid-flow coating technique were employed to form the silver and dielectric layers inside the fused glass capillary tube for the simplicity, lower cost and potentiality of mass-production. Hollow waveguides with the length of 2m, and the inner diameters of 700 μm and 1mm have been successfully fabricated. It is shown that COP- coated silver hollow glass waveguides can be used to transmit Er:YAG, CO, and CO2 laser light with low losses when the thickness of COP layer is properly chosen. The measured spectra in the visible and mid-IR regions also show that uniform films were deposited inside the tube. Comparisons were also made among the waveguides that were inner-coated with other dielectric materials used before.
