Abstract
Hollow glass waveguides are an attractive fiber delivery system for both the 3 micrometers Er:YAG and 10.6 micrometers CO2 lasers. The losses for these waveguides are as low as 0.2 dB/m at CO2 laser wavelengths for guides with a 700 micrometers bore. At the shorter wavelengths of the Er:YAG laser the losses are higher than those predicted theoretically. This is shown to be a result of surface roughness of the inner coatings. These hollow guides are found to have losses which change little with time or cyclic flexure. A new version of these guides made from polycarbonate tubing is described and the losses for these guides are shown to compare favorably with those for the glass guides.
