A vortex Raman laser pumped by the second-order optical vortex mode was demonstrated. The first-and the second-Stokes waves that lased at the first-order optical vortex mode were generated. Considering the spatial intensity overlap between the pump and the first-Stokes beam, and between the first-and second-Stokes beams, the generation of a topological charge of 1 in the Stokes fields could be theoretically predicted.
