Description/Abstract

UV generation in optical fibres has long been deemed challenging because of lack of suitable lasing ions in the UV and the poor transparency of germanosilicate fibres at wavelengths shorter than lambda =400nm.
In our experiments, optical fibres with pure silica core and fluorosilicate cladding have been used, providing a loss smaller than 1dB/m at lambda <300nm. Two different techniques were used to achieve light generation at lambda <400nm: nonlinear optics in tapered optical fibres with sub-micrometric diameter (nanofibers) and doping with rare-earths.
