Author Affiliations +
Many medical applications have need of 'broad' irradiation patterns, but benefit from small diameter fibers to provide minimal invasive surgery. These applications also benefit from using the low intrinsic loss character of silica based core material as well as the power capability of a silica/silica construction. Pure silica core, all silica optical fibers are now available with an NA of 0.30 ± 0.02. Variations include fibers with non-solarizing ultraviolet transmissions as well as fibers with transmission through the near infrared [IR] region of the electromagnetic spectrum. Additionally ultra high NA fibers with silica cores and silica/silica structures are now available for use in the visible and near IR regions with effective NAs higher than 0.6. Properties of these fibers are presented and the advantages over other fibers and potential medical applications are also discussed.
