Abstract
Photobleaching at 1.30 by 1.30-micron transmitted light during and following exposure to Co-60 irradiation is evaluated at -55 C in undoped and doped silica fibers. It is found that photobleaching can reduce radiation-induced attenuation by a factor of ten with an irradiance as low as approximately 0.1 W/sq cm in fibers where the 630-nm drawing-induced band is absent. This low-temperature photobleaching is characterized by high-order recovery processes. Little photobleaching was observed in germanium doped fibers until irradiances were above 100 W/sq cm.
