Abstract

Hollow core waveguides are becoming a potential delivery system of high power CO₂ laser for applications in medical and material processing procedures. GeO₂ as a kind of cladding material of hollow waveguide with low loss at the wavelength of CO₂ laser, has been studied recently. As we know, loss in hollow waveguide increases because of bending, twisting and other reasons. In this paper, bending losses in hollow core GeO₂ waveguide were measured by bending the waveguide for known radius of curvature, the bending plane was parallel or perpendicular to the polarization of CO₂ laser beam. We also compared our results with those of GeO₂-based hollow waveguide.
