Paper Abstract

We demonstrate that second harmonic generation obtained in Ge-doped holey fibres can act as a seed for visible supercontinuum generation. This spectral enlargement is obtained by means of a double-pumping system. By using a microchip laser source delivering sub-nanosecond pulses at 1064 nm and a highly Ge-doped fibre, we obtain a second harmonic generation efficiency of 4.8 % after an optical poling process. A white light continuum extending on more than 250 nm is obtained in visible domain.
