Abstract
Radiation response of thick multimode Ge, P, F-doped quartz fiber has been examined after exposure to 60Co gamma-source within a dose interval of 10 - 107 Gy at a dose power of 2.3 and 24 Gy/s at 300 K. The induced transparency losses A at the wave length of 1.06 micrometers do not exceed 0.2 after a dose of 106 Gy and reach a saturation, while the fibers are closed for visible light after a smaller dose. Varying focus and an angle of leading a probe light beam in fiber, the core modes were found to close at a dose of 104 Gy due to radiation induced color centers of Ge and non-bridging oxygen O-, and the clad modes were suppressed at 500 Gy by the expense of Al impurity color centers.
