Abstract

Hollow glass waveguides are an attractive fibers delivery system for a broad range of IR wavelengths, including the 3 μm Er:YAG and 10.6 μm CO₂ lasers. The losses for these waveguides are as low as 0.2 dB/m at the 10.6 wavelength for waveguides with a 700 μm bore. At the shorter wavelengths, like that of the Er:YAG laser, losses are higher than those predicted theoretically. This is shown to be a result of the increasing effect of surface roughness of the inner coatings. Variation of attenuation from waveguide to waveguide is examined, and the variation in the dielectric layer is evaluated.
