title: Photoinduced second-harmonic generation in gamma-ray-irradiated optical fibers.
abstract: The effect of gamma-ray irradiation on photoinduced second-harmonic generation in optical fibers is investigated for the first time to our knowledge. A significant increase (by a factor of 20) in the conversion efficiency of gamma-ray-irradiated optical fibers is found. An explanation of the experimental results is suggested, which is based on the photovoltaic mechanism of the photoinduced second-harmonic generation.
