Abstract

The vector vortex mode generation from a Ba(NO3)2 Raman laser cavity pumped by a vector LG02 green laser was demonstrated. The 1st, 2nd, 3rd, and 4th Stokes outputs operated at a radially polarized mode. The maximum output energies of the 1st, 2nd, 3rd, and 4th Stokes were measured to be 0.33 mJ, 0.50 mJ, 0.32mJ and 0.03 mJ, respectively, at the maximum pump energy of 4.39 mJ.
