Abstract

We investigated pulsed X-ray-induced attenuation in two pure-silica-core (PSC) optical fibers with low-chloride (Cl) and different hydroxyl (OH) contents. We measured at room temperature the temporal (100 ms-1000 s) and spectral (0.73-3.1 eV) variation of the induced optical absorption after a 1 MeV X-ray pulse in both low- and high-OH PSC multi-mode fiber samples. A component of the transient loss in the low-OH sample was found to comprise absorption bands at 1.63 and 1.88 eV (760 and 660 nm) arising from self-trapped holes (STHs). Already known to be instable at room temperature, STSs appear to play a key role in the transient responses of low-OH/low-Cl pure-silica-core fiber in the visible/near-infrared part of the spectrum.
