Fabrication and transmission properties of ZnS-coated Ag waveguides for Er:YAG CO and CO2 laser light

摘要

Abstract: Fabrication process and transmission properties of nontoxic and durable ZnS-coated silver waveguides have been described. By suitably choosing the thickness of ZnS layer, hollow waveguides have been realized to transmit Er:YAG, CO, and CO$-2$/ laser light simultaneously or independently with low-losses. A glass- based mandrel is employed in the fabrication process to improve an output beam quality from the waveguide. !5
