Delivery system for high-energy pulsed ultraviolet laser light

摘要

The transmittance of high peak energy ultraviolet laser light that is conducted within a silica fiber-optic waveguide is increased by doping the silica with a material that functions to repair inherent structural defects in the silica. Preferred materials include one or both of an OH- radical and fluorine. The silica is synthetic silica that is substantially free of metallic impurities. The cladding for the waveguide is made of an organic material rather than glass.
