Transmission properties of pure silica fibers for delivery of UV laser

In this paper, the transmission properties of the demostic pure silica fiber, of which the core diameter ranges from 300 micrometers to 800 micrometers , are investigated. The properties include laser induced surface and bulk damage thresholds, transmission losses, curved characteristics, degeneration when the fibers are irradiated by UV laser and so on. These studies are helpful to improve technology of manufacturing fibers and make wider and more successful application in medicine.
