ABSTRACT
In this article, the design and characteristics of a micro-fadeometer is presented. The technique allows for a non-(micro-) destructive evaluation of the light fastness of colorants on various materials and can be used to directly assess valuable materials, such as heritage objects, and develop safer display strategies to promote their preservation. The presented instrument has several benefits over standard light ageing methods - low operating cost, non-damaging, real time measurement of induced changes for kinetics studies, and automated high throughput screening of materials. A selection of data is presented to demonstrate the flexibility of the presented instrument and illustrate how it can be used to evaluate museum lighting and oxygen-free display of heritage objects.

    We experimentally investigate a high output power L-band (1565-1605 nm) erbium-doped fiber amplified spontaneous emission (ASE) source using dual forward-pumping configuration. Such configuration allows high pumping-power operation and enhances the pumping efficiency. The high pumping efficiency...
