Abstract

Flexible 100-μm-bore hollow fibers were developed for Er:YAG laser delivery. The hollow fiber was inner coated with silver and dielectric layer to enhance the reflection rate at an objective wavelength band. A dielectric layer is formed by using the liquid-phase coating technique. Micro tube pump with an inner diameter of 300-μm is newly used to flow polymer solution through the ultra-thin silver hollow fiber with a constant speed. Fabrication process and transmission properties of the ultra thin polymer-coated silver hollow fiber were discussed. The loss for the 100-μm-bore size, 10-cm-length polymer-coated silver hollow fiber was 1.7 dB at the wavelength of 2.94 μm.
