- Abstract
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 × 10[sup 12] cm[sup -2] (9 Gy); dose rate, <7 × 10[sup 16] cm[sup -2] s[sup -1] (1.1 × 10[sup 5] 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.
