摘　　要：Perfect vector beams are a class of special vector beams with invariant radius and intensity profiles under changing topological charges.However,with the limitation of current devices,the generation of these vector beams is limited in the visible and infrared wavebands.Herein,we generate perfect vector beams in the ultraviolet region assisted by nonlinear frequency conversion.Experimental and simulation results show that the radius of the generated ultraviolet perfect vector beams remains invariant and is thus independent of the topological charge.Furthermore,we measure the power of the generated ultraviolet perfect vector beams with the change of their topological charges.This study provides an alternative approach to generating perfect vector beams for ultraviolet wavebands and may promote their application to optical trapping and optical communication.
