A　dual　sub-pulse　train　1064　nm　picosecond　radially　polarized　beam　pump　KGW　single-pass　Raman　generator　was　designed.　The　Stokes　lines　of　both　the　768　cm(-1)　and　901　cm(-1)　vibrational　modes　of　the　KGW　Raman-active　crystal　were　excited　simultaneously.　The　Raman　generator　radiated　up　to　seven　Stokes　lines　in　the　infrared　spectrum,　which　covered　multiple　optical　communication　channels.　The　overall　Stokes　average　power　reached　1.01　W,　and　the　maximum　Raman　overall　conversion　efficiency　was　23.1%.　The　interaction　between　the　optical　field　and　the　Raman　crystal　was　discussed　from　two　perspectives　of　line　width　compression　and　beam　quality.
