In this work we study the effect of the ring width on the performance of a ring generated Bessel beam. Experimental results and simulation model for ring generated Bessel beams are investigated and compared. The simulation model is based on Fourier optics. The effect of varying the ring radius and the ring width on the Bessel beam parameters like the axial intensity and the detected output power transported by the beam passing through the ring is studied. A good agreement is found between the simulation model and the measurements. Larger ring width led to higher efficiency (output power) but to less beam quality.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
