Transmission characteristics of fluorocarbon-polymer-coated silver hollow glass waveguides for Er:YAG laser light

2 m-long and small-bore fluorocarbon polymer -coated silver hollow glass waveguides have been fabricated by using all liquid phase process and their transmission properties have been experimentally analyzed. The total straight transmission losses for the single-shot Er:YAG laser light were measured as about 0.4 dB and 1.0 dB for 2 m-long hollow waveguides with the inner diameters of 700 micrometers and 540 micrometers , respectively.
