CW high power 1.24 /spl mu/m and 1.48 /spl mu/m Raman lasers based on low loss phosphosilicate fibre

摘要

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