Abstract

A variety of optical systems use high optical powers or energies, for example, power transport. These systems may be expected to operate in harsh and challenging environments, which may include ionizing radiation. In this paper, several different types of modern, commercially available optical fiber designs have been assessed for reliable operation in a transient gamma radiation environment. The fibers tested are large core multimode silica fibers optimized for the delivery of high power infrared laser light. Some of the fibers are specifically designed to operate in harsh radiation environments, and these are compared against designs of varying radiation resilience from other manufacturers. It was found that fibers were able to successfully transmit a laser pulse of up to 0.375 MW in peak power within a few hundred nanoseconds after irradiation, with less than a 10% loss in transmission.
