The light emission intensity at the wavelength of 400-750 nm in the KU-1 silica core (OH content 1000 ppm) fiber waveguide under irradiation at BARS-6 pulsed fission reactor (pulse duration 80 microsecond(s) , dose per pulse <5.5x1012 n/cm2 (9 Gy), dose rate <7x1016 n/cm2s (1.1x105 Gy/s) have been measured. The intensity of radiation-induced light emission has been found to depend on intensity of probing light. Lower intensity of the light emission has been observed for higher intensity of probing light (lasers, wavelength 532 and 632 nm). The light emission quenching occurs at the wavelengths shorter and longer than the wavelength of the probing light, and also at the equal wavelengths.
