摘要：
The radiation induced optical transmission loss of heat-treated fused silica core optical fibers has been investigated under gamma-ray irradiation. Observed radiation induced transmission loss indicated temperature dependence, which suggests that the behavior of radiation induced defects responsible for the transmission loss depend on heat-treatment temperatures before irradiation. As a result, the optical fibers heat-treated at 200 degreesC had the most radiation resistance among those investigated. We propose that an optimum temperature for developing radiation resistance should exist and might be near 200 degreesC. (C) 2004 Elsevier B.V. All rights reserved.
