Paper Abstract

We reported on high average power ultraviolet (UV) picosecond optical vortex generation without any spatial separation of the phase singularity due to the walk-off effect by employing a pair of β-BaB2O4 and reversed β-BaB2O4 crystals. The UV vortex output power was measured to be 1.76 W, corresponding to the optical-optical conversion efficiency of 17 %.
