Abstract

ZnS-coated Ag hollow waveguides for Er:YAG, CO, and CO(2) laser light are fabricated based on a sputtering and an electroplating technique. Three types of these waveguides with a 1-mm diameter and a 1-m length are fabricated. Two of them are designed to achieve the minimum loss at the wavelengths of Er:YAG and CO laser light, and the other is for all the lasers. Straight losses of 0.4, 0.5, and 0.25 dB/m are obtained for Er:YAG, CO, and CO(2) laser light, respectively. Because the waveguides are flexible and low loss, they are useful in delivery of mid-infrared lasers in industrial and medical applications.

摘要

基于溅射和电镀技术制备了用于铒钇铝石榴石（Er:YAG）、一氧化碳（CO）和二氧化碳（CO₂）激光的硫化锌包覆银空心波导。制备了三种直径为1毫米、长度为1米的此类波导。其中两种设计用于在Er:YAG和CO激光波长下实现最小损耗，另一种适用于所有这些激光器。对于Er:YAG、CO和CO₂激光，分别获得了0.4、0.5和0.25 dB/m的直线损耗。由于这些波导具有柔韧性且损耗低，它们在工业和医疗应用中用于中红外激光的传输方面很有用。
