研制了用于Er：YAG激光传输的100 μ m口径柔性中空光纤。中空光纤的内部涂覆有银和电介质层，以提高在目标波段的反射率。通过使用液相涂覆技术形成介电层。采用内径为300 μm的微管泵，使聚合物溶液以恒定的速度流过超薄银中空纤维。讨论了超薄型聚合物包覆银中空光纤的制备工艺和传输特性。在2.94 μm波长处，内径为100 μ m、长度为10 cm的聚合物包覆银中空光纤的损耗为1.7 dB。
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.
