Abstract

Both the magnitude of the ionizing radiation-induced loss near 850 nm during steady state ⁶⁰Co irradiation and the rate of recovery after the cessation of radiation may be influenced by the 850-nm optical power level being transmitted, a photoenhanced recovery called the photobleaching effect.¹ The effect is especially intense in fibers with pure silica cores and in those at lower temperatures.²
