Abstract

Flexible hollow-glass fibers with small-bore diameters of 250 and 320 µm have been developed for Er:YAG laser delivery. The fibers consist of a glass capillary tube and an inner coating of silver and polymer thin films that are deposited by use of a simple liquid-phase technique. The 250µm-bore fiber exhibits a straight loss of 0.8 dB/m and a bending loss of 1.2 dB when it is bent 180° at the output end, with a bending radius of 2 cm. The maximum energy delivered by the fibers is 100 mJ.
