Fiber lasers and laser amplifiers at 1 m wavelength are already a fundamental tool for materials processing. Their reliability and efficiency allow precise and cost-effective welding, cutting, trepanning (drilling), and engraving as well as micromachining or more exotic applications such as material forming (i.e., shaping) of 3D prototypes. The next generation of fiber-laser applications will include cost-efficient production of solar cells by 13nm lithography. However, such technology will… Expand

Impact of photodarkening on Yb lifetime in Al-silicate fibres and on the rate-equation system
In this paper we report our investigation on the lifetime reduction in ytterbium doped aluminosilicate fibers due to the pump induced photodarkening (PD). We show a linear correlation betweenExpand


Measuring photodarkening from single-mode ytterbium doped silica fibers.
A fast, simple and repeatable method to measure and compare the photodarkening rate caused by the formation of photoinduced structural transformations from Yb-doped single-mode fibers is presented. Expand
Concentration dependence and self-similarity of photodarkening losses induced in Yb-doped fibers by comparable excitation.
Self-similarity of loss evolution when experimental curves are simply normalized to fitting parameters is demonstrated, which supports the possibility of introducing a preliminary figure of merit for Yb-doped fiber. Expand
Characterization of photodarkening processes in Yb doped fibers
The time-dependence of photodarkening (PD) in Yb-doped fibers is commonly fitted with a stretched exponential function to determine typical parameters of the process. But, the experimental conditionsExpand
Self-similarity of time evolution of photodarkening losses induced in Yb-doped fibers and photodarkening figure of merit
In this paper we report and summarize an extensive investigation of photodarkening in Yb-doped silica fibers. We made a set of similar fibers in order to cover a large Yb concentration range. TheExpand
Lifetime quenching in Yb-doped fibres
Abstract We have discovered that in ytterbium-doped silica fibres of different compositions the excited state lifetime of a fraction of the Yb ions (between 1% and over 90%) is quenched to a veryExpand
Improved photodarkening resistivity in ytterbium-doped fiber lasers by cerium codoping.
It is suggested that the coexistence of the redox couple Ce(3+)/Ce(4+) in the glass provides means for trapping both hole- and electron-related color centers that are responsible for the induced optical losses in Yb-doped fiber lasers. Expand
Highly nonlinear near-resonant photodarkening in a thulium-doped aluminosilicate glass fiber.
The result shows that absorption of infrared light of moderate intensity can lead to photoionization in rare-earth-doped glass, provided that a multiphoton stepwise excitation channel exists. Expand
