Paper Abstract

Heat-resisting polyimide-coated silver hollow glass waveguides have been fabricated for infrared medical laser light transmissions. The waveguides have inner diameters of 700 and 530 micrometers and the length of 1 m. The measurements of the guiding loss spectra show the low-loss property of the waveguides at the desired wavelengths. Moreover, Er:YAG laser light has been transmitted by the 700 micrometers -bore waveguide with the losses as low as 2.2 dB even when the waveguide is bent with a bending radius of 15 cm (180 degree(s)-bend).
