Abstract
The radiation resistance of undoped and F-undoped synthetic silica is investigated at 840 nm and 1308 nm wavelength. At both wavelengths the F-doped silica shows improved radiation resistance compared to that of the undoped water-free silica. The recovery behaviour after pulsed irradiation of both materials can be devided into three phases with different recovery coefficients. Our results are compared with those from earlier work.
