Simultaneous effects of photo- and radio- darkening in ytterbium-doped aluminosilicate fibers

چکیده
We present original characterizations of photo-radio-darkening in ytterbium-doped silica optical fibers submitted to the simultaneous action of the pump and of an ionizing radiation. We present the interplay between both radiations, showing e.g. that the pump is able to darken or bleach the fiber depending on the ionizing dose. The photoresistance of the fiber is shown to play a crucial role on its radio-resistance, and that photo-resistant fibers should be also radio-resistant in low dose rate conditions. All the results are thoroughly explained by a physical model presented in a separate article by Mady et al. (this conference proceeding).

A physical model of the photo- and radiation-induced degradation of ytterbium-doped silica optical fibres
We propose a model to describe the photoor/and the radiation-induced darkening of ytterbium-doped silica optical fibers. This model accounts for the well-established experimental features of photo-darkening. Degradation behaviors predicted for fibers pumped in harsh environments are also fully confirmed by experimental data reported in the work by Duchez et al. (this proceeding), which gives a ...
متن کاملThermoluminescence characterization of traps involved in the photodarkening of ytterbium-doped silica fibers.
The photodarkening (PD) mechanisms of ytterbium-doped silica optical fibers have still not been elucidated, although hardening routes have been proposed. Most basic questions are still under debate about the assignment of the darkening excitation bands into the UV range, the nature of absorbing centers (photoionized centers or trapped carriers?), or of traps accepting photo-released carriers (e...
متن کاملInfluence of the Substrate tube Quality on TSL Features of Yb-doped Silica Preforms of Optical Fibres
We have demonstrated by spectral analysis of thermally stimulated luminescence that depending on the quality of the substrate-tube used during the MCVD technique, Ybdoping of silica preforms might be responsible for both the formation of the non-bridging hole centres (NBOHC) and their amount within the final preform. If these centres as well as those originating from the substrate tube are stil...
متن کاملImproved Setup and Procedure for Benchmarking of Photodarkening in Ytterbium Doped Silica Fibers
This paper presents a new setup and a corresponding procedure for the accurate measurement of photodarkening in ytterbium doped fibers. The core-pumping scheme enables the use of short samples and a low pump power and the automation of the measurement permits long-term tests for an effective benchmarking of fibers with low photo-degradation. Exploiting temperature-controlled components and cohe...
متن کاملSol-Gel Derived Active Material for Yb Thin-Disk Lasers
A ytterbium doped active material for thin-disk laser was developed based on aluminosilicate and phosphosilicate glass matrices containing up to 30 mol% YbO1.5. Thick films and bulk samples were prepared by sol-gel processing. The structural nature of the base material was assessed by X-ray diffraction and Raman spectroscopy and the film morphology was evidenced by scanning electron microscopy....
