IR-induced photodarkening in Tm-doped fluoride fibres

By P.R. Barber, R. Paschotta, A.C. Tropper and D.C. Hanna

Abstract

We have observed a new type of infrared-induced photodarkening in high-numerical-aperture fluoride fibers doped with 3000 and 10,000 parts in 10^6 by weight of Tm. The loss induced in the visible region by 1140-nm radiation is very strong (as high as 25 dB in a 50-cm piece) and broadband it can be removed by irradiation with the same pump wavelength at lower powers
