N2 - We demonstrate for the first time a fibre Raman laser delivering record-setting energy (60 nJ) of double-scale picofemtosecond pulses at wavelength of 1270 nm, which is of great interest in bio-medical applications. A Stokes wave was generated in single-stage Raman conversion of amplified radiation from a mode-locked F8 Yb-doped laser passing through a synchronously pumped phosphosilicate fibre ring cavity. The converted radiation at 1270 nm amounting to 47% of the total Raman laser output was maximised by tuning the repetition rate of the pulses generated in the Yb-doped master oscillator to the fundamental inter-mode spacing frequency of the phosphosilicate fibre cavity.
