摘要：
The radiation-induced visible emission (400–750 nm) intensity in an optical fiber with a KU-1 silica glass core (OH group content, 1000 ppm) was measured in the fiber irradiated in a pulse mode [BARS-6 reactor; pulse duration, 80 μs; dose per pulse, <5.5×1012 cm−2 (9 Gy); dose rate, <7×1016 cm−2 s−1 (1.1×105 Gy/s)]. The fiber probed by laser pulses (at 532 and 632 nm) with increasing intensity showed a decrease in the radiation-induced emission intensity in the regions of wavelength both greater and lower than and equal to the probing light wavelength.
