Abstract
The paper presents the design and preliminary experimental validation of a fiber laser with direct emission in the yellow, which has been developed within the "Yellow-FLiCkEr" project, funded by the Italian Ministry of University and Research. The laser uses Dy-doped soft-glass fibers, both commercial and ad-hoc custom made. The pump is provided by high-power blue laser diodes and the mirrors are Bragg gratings directly inscribed in the soft-glass fiber with a femtosecond laser. Suitable models have been developed both to optimize the laser behavior and to study the laser-eye tissue interaction. Preliminary studies with cultivated cells have demonstrated the laser's potential for ophthalmology.
