Abstract

We employ an off-center pumped Nd:YVO4/KGW Raman laser with stimulated Raman scattering and second-harmonic generation to generate high-order structured beams at 588 nm. The orange structured lights are transformed by using an external astigmatic mode converter for producing multiple optical vortices. We further verify that the experimental multi-vortex beams can be numerically reconstructed with the theoretical model, and the distribution of vortices is demonstrated by analyzing the phase structures of the converted beams.
