In this paper the generation of highorder Bessel beams by focusing the vortex beams with an axicon is presented.The intensity distribution of vortex beams after being focused by the axicon was simulated.It is shown that after being focused by the axicon,a vortex beam can be converted into the high order Bessel beam.Moreover,the order of the Bessel beam is equal to the topological charge number of the vortex beam.The generation of the high order Bessel beam was also experimentally investigated.Th...
