Transient response of optical fibers exposed to pulsed radiations
Abstract
Transient radiation darkening and recovery were measured by bremsstrahlung and electron-beam radiation at room temperature in seven commercial glass fibers. Fiber responses during and after the radiation pulse were reduced to delta function response parameters by curve fitting; most fibers showed a complete recovery suggesting the presence of multiple anneal mechanisms with different characteristic times. At temperatures between 216 and 247 K, most fibers demonstrated increased darkening and slowed recovery rates.
