摘要

The Stokes line of multi-mode Raman laser was limited by low conversion efficiency of higher-order Stokes and the competition between pure cascaded stimulated Raman scattering (SRS) and Four-wave-mixing (FWM) process which will deplete the pump of SRS process.Through developed pulse-train synchronously pumping technique and two-Raman-mode operating,the orders of output Stokes was improved.With average power of 220mW,the developed a Raman laser providing up to 5 orders Stokes output,containing up to 16 laser lines without tuning operating and four-wave-mixing process.
