Abstract

We demonstrate intracavity frequency doubling of the self-Raman field generated within a diode end-pumped, solid state Nd:GdVO4 vortex laser. A maximum output power of 727 mW is generated at 586 nm with an overall diode-to-yellow conversion efficiency of 4%. Conservation of orbital angular momentum is observed under intracavity frequency doubling, with the topological charge of the yellow beam being twice that of the Stokes beam.
