Transient Radiation Induced Attenuation And Luminescence In Optical Fibers

This paper addresses two effects of transient irradiation on optical fibers. The recovery of the induced attenuation was measured from 100 ns to 1 ms in several fibers, including two pure silica fibers and three fibers with doped silica cores. Measurements were performed at various optical power levels up to 28 mW at -55 and 23 C to investigate the temperature dependence and possible photobleaching effects at short times. We also report studies of the luminescence induced by the transient irradiation for the same group of fibers.© (1989) COPYRIGHT SPIE--The International Society for Optical Engineering.
