Abstract :
The authors propose a new simple configuration for 1.24 and 1.48 μm Raman fibre lasers which are promising pumping sources for 1.31 μm Raman amplifiers and Er-doped fibre amplifiers, respectively. Efficient resonant conversion of CW 1.06 μm radiation to the first (1.24 μm) and second (1.48 μm) Raman Stokes in a phosphosilicate fibre is demonstrated for the first time
